One embodiment of a method includes loading, by a memory controller, a boot image from a solid state drive to an operating memory of a computing system during an initialization operation of the computing system. The initialization operation initializes components of the computing system.

Method of managing a solid state drive, associated systems and implementations

Described is a memory controller interfacing with a host and a nonvolatile memory. The memory controller may include a buffer unit configured to store an input address table and a first hot address table; and a processing unit configured to judge whether an address from the host coincides with one of addresses stored in the input address table and to store the address from the host in the first hot address table according to the judgment.

Memory controller controlling a nonvolatile memory

Disclosed is a memory device which comprises a data storing part having plural physical storage spaces; and a control part for storing data in the data storing part, wherein each of the physical storage spaces comprises a main area for storing user data at a write operation and a spare area for storing additional data other than the user data, the additional data including a logical address corresponding to a physical storage space and a link value indicating a physical storage space to be accessed next.

Memory device, memory system and mapping information recovering method

A storage device includes a flash memory, a buffer memory and a memory controller. The buffer memory is configured to temporarily store write data to be written in the flash memory, the buffer memory including volatile RAM and non-volatile RAM. The memory controller is configured to select one of the volatile RAM and the non-volatile RAM to temporally store the write data based on a write pattern of the write data, and to transmit a host command complete signal to a host when the write data is stored in the non-volatile RAM.

Storage device with buffer memory including non-volatile RAM and volatile RAM

A method is provided for operating a data storage device comprising a storage medium and a controller configured to control operations of the storage medium. The method comprises determining whether a read-requested data strip is an error data strip, reading a plurality of data strips in a stripe comprising the read-requested data strip when the read-requested data strip is the error data strip, outputting a data strip recovered using the other data strip except the error data strip among the plurality of data strips, and writing the recovered data strip and the other data strips into the storage medium.

Data storage device related method of operation

A memory system is provided with a processor, a main memory, and a flash memory. Performance of the memory system is improved through achievement of speed-up and high data reliability. The memory system includes a nonvolatile memory device and a controller configured to drive a control program to control the nonvolatile memory device. The control program executes a second access operation for the nonvolatile memory device even before a first access operation to the nonvolatile memory device is completed.

Memory system and method of accessing a semiconductor memory device

A method of writing data in a memory system comprises determining a characteristic of write data and generating characteristic information according to the determined characteristic, generating a write command corresponding to the write data, and sending the write command, the characteristic information, and the write data to the memory system.

Method and apparatus for writing data in memory system

A storage apparatus includes a memory unit and a controller to set up a memory space of the memory unit as a user data space and a spare space according to a signal representing at least one of the user data space and spare space. An electronic apparatus controls the storage apparatus, and a method controls at least one of the storage apparatus and the electronic apparatus to control a memory space of the storage apparatus.

Defining and changing spare space and user space in a storage apparatus

A solid state drive may include one or more memory cell arrays divided into a plurality of blocks. A first portion of the blocks may be designated for storing user data and a second portion of the blocks may be designated as reserved blocks for replacing defective blocks in the first portion. In one embodiment, the method includes reformatting, by a memory controller, the solid state drive to convert one or more blocks in the first portion into reserved blocks.
