The present invention relates to a method for addressing the memory locations of a memory card. There are several memory locations in a memory card for storing data, in which case in order to address a specific memory location an address is formed. At least one parameter is stored in the memory card, on the basis of which parameter the number of memory locations of a memory card can be calculated, and a specific number of bits is reserved for said at least one parameter. In the method, two or more memory locations are addressed with one address, and/or the number of bits that can be used in an address is increased. The invention also relates to a system and a memory card in which the method is applied.

Method for addressing a memory card, a system using a memory card, and a memory card

A device, a computer readable medium, and a method are provided. The device includes, but is not limited to, a sensor, a processor, a non-volatile memory, and a computer-readable medium. The computer-readable medium includes, but is not limited to, computer-readable instructions stored therein that, upon execution by the processor, perform operations comprising initiating a write operation of data to the non-volatile memory; during the initiated write operation, monitoring the sensor to determine if the electronic device is falling; and if the electronic device is determined to be falling, interrupting the initiated write operation and executing a non-volatile memory shutdown procedure.

Protection of non-volatile memory component against data corruption due to physical shock

A method and system for data transfer between a sector-oriented mass storage medium and a host device capable of interfacing with a byte-oriented storage medium using an HS-MMC physical interface in the host device. Existing MMC commands such as FAST_IO command can be used to pass the control data to the sector-oriented mass storage medium and also to read the status of that medium. It is possible to use the GEN_CMD command for data transfer, for example. Because the command in data transfer is similar to ATA protocol, ATA write commands and ATA read commands can also be used for data transfer to and from the sector-oriented mass storage medium.

This invention relates to a method permanently write protecting a portion of a memory card. According to the invention a bit indicating permanent write protection or permanent write protection of a portion of the memory card is set in the specific data register of the memory card to indicate that all the write protect groups protected with write protecting command are permanently write protected. In another embodiments of the invention special commands are used to control the write protection of the portion of the memory card. This invention also relates to a partially permanently write protected memory card. The invention further relates to an electronic device, a software, a system and a module utilizing the method of the invention.

Systems and methods for booting a host device(s) from a peripheral device(s), via an interface, such as an MMC/SD interface, with power terminals, a data bus with data bus terminals, a clock line with a clock terminal and a command line with command terminal. Power is provided to the power terminals, and the command terminal of the MMC/SD or analogous interface is set during power-up to low. The data bus is monitored for a start bit of data transmission.

A terminal () is shown with a memory () for storing a file (F), means () for selecting a file (F) to be deleted, and means () for marking the file selected to be deleted as deleted. A system comprises at least one second device () with a memory () with a storage location () for files marked as deleted, for storing files marked as deleted in the terminal (). The terminal () is provided with a storage location () for storing at least a part of the data of the file (F) marked as deleted, and means () for transmitting at least a part of the file marked as deleted, to be stored, if necessary, in the storage location () in the second device () for files marked as deleted. A method for managing files and a computer software product are also shown.

Arrangement for processing data files in connection with a terminal

A method, system, device and software products for loading files or clips thereof from a unit including files or clips thereof over at least one interface to a data-processing unit. The arrangement according to the invention includes determining joint probabilities of the files or parts ('clips') thereof, energy consumptions caused by their loading and a value for maximum energy consumption. A loading order is formed for the files or clips thereof as a function of the joint probabilities. Files or clips thereof are loaded over at least one interface in the loading order, and total energy consumption caused by the loading is determined until the value of the total energy consumption exceeds the value of the maximum energy consumption. At this point, loading of the files or clips thereof is interrupted.

Predictive probability arrangement for loading files over an interface

The specification and drawings present a new method, apparatus and software product for performance enhancement of a memory device (e.g., a memory card) using a pre-erase mechanism. The memory device can be, e.g., a memory card, a multimedia card or a secure digital card, etc. A new command or commands can be used to inform a memory device controller when the data in one particular sector, allocation unit or block can be deleted. Using that information the memory device controller then can be able to do some internal maintenance, e.g., by moving valid data from a fragmented erase block to another so that the fragmented erase block can be cleared and erased for future use as well as performing effective wear leveling maintenance and write performance optimization.

Memory device performance enhancement through pre-erase mechanism

The invention relates to a method for use in a system comprising a host device and at least one peripheral device which are enabled to interact with each other. In order to improve the flexibility of the system, the method comprises a step of transmitting information indicative of a time required for an initialization of the at least one peripheral device from the at least one peripheral device to the host device, and a step of evaluating in the host device the information indicative of a time required by the at least one peripheral device for an initialization. The invention relates equally to a corresponding host device, to a corresponding peripheral device, to a corresponding system and to corresponding software program products.

This invention provides a method to operate a terminal (), as well as a terminal that operates in accordance with the method. The method includes, in response to initiating a data write operation with a non-volatile memory device (), activating a sensor () that is capable of detecting that the terminal is falling; during the write operation, monitoring the sensor to determine if the terminal is falling and, if it is determined that the terminal is falling, terminating the write operation and executing a non-volatile memory shutdown procedure, else, if it is determined that the terminal is not falling, completing the write operation and deactivating the sensor.

A method, system, device and software product for comparing the contents of memory components in electronic devices. A data transmission connection is established between the electronic devices, and device identifiers and checksum values are determined in the electronic devices. An initialization message is transmitted from a first electronic device to a second electronic device, the message comprising a device identifier and a checksum value. The device identifiers of the first and a second electronic device and the check-sum values are compared with each other, as a result of which the contents of the memory components are caused to correspond to each other, or the contents of the memory components are noted to correspond to each other.

Method for comparing contents of memory components

The invention relates to a method of operating a storage component. In order to enable a verification of the integrity of the data in the storage component, it is proposed that first a write operation for storing data in a data storage areaof the storage componentis performed. Then, a completion status fieldin the storage componentis updated, in case the write operation has been completed successfully. The updated completion status fieldindicates that the write operation has been completed successfully. The invention relates equally to a corresponding storage component and to a corresponding system.
