Provided are an apparatus, system and method to determine whether to use a low or high read voltage. First level indications of write addresses, for locations in the non-volatile memory to which write requests have been directed, are included in a first level data structure. For a write address of the write addresses having a first level indication in the first level data structure, the first level indication of the write address is removed from the first level data structure and a second level indication for the write address is added to a second level data structure to free space in the first level data structure to indicate a further write address. A first voltage level is used to read data from read addresses mapping to one of the first and second level indications in the first and the second level data structures, respectively. A second voltage level is used to read data from read addresses that do not map to one of the first and the second level indications the first and second level data structures, respectively.

Apparatus, system, and method to determine a demarcation voltage to use to read a non-volatile memory

A first set representing a first plurality of physical block addresses of a non-volatile memory and a second set representing a second plurality of physical block addresses of the non-volatile memory may be identified. In response to a request to perform a wear leveling operation, first data from a first physical block address of the first set may be swapped with second data from a first physical block address of the second set. A second physical block address of the first set that is adjacent to the first physical block address of the first set may be identified. Third data from the second physical block address of the first set may be swapped with fourth data from a second physical block address of the second set that is adjacent to the first physical block of the second set.

Wear leveling based on a swapping operation between sets of physical block addresses of a non-volatile memory

A mechanism is described for facilitating power governance of non-volatile memory devices using a power governing mechanism employed at a computing device according to one embodiment of the invention. A method of embodiments of the invention includes maintaining a credit pool having a plurality of credits to be released to a plurality of memory channels associated with a plurality of non-volatile memory devices. The plurality of credits may be used to provide sufficient power to perform memory operations associated with a computing device. The method may further include receiving a credit request having a petition to obtain one or more credits for a memory channel of the plurality of memory channels to facilitate performance of a memory operation, determining whether the one or more credits are available in the credit pool, and retrieving the one or more credits from the credit pool, if the one or more credits are available in the credit pool. The method may further include releasing the one or more credits to the memory channel. The one or more released credits are used to perform the memory operation.

Mechanism for facilitating power and performance management of non-volatile memory in computing devices

A circuit for sensing on-die temperature at multiple locations using a minimum number of pins is described. Thermal diodes coupled to pins are placed on a die to measure the temperature at various die locations. Voltage is applied to the pins to determine the temperature at each given diode location. The polarity of the voltage applied across the pins determines what diodes are selected for measurement.

Circuit for sensing on-die temperature at multiple locations

A system may include a first diode and a device coupled to the first diode. The device may be adapted to transmit a first current through the first diode, to determine a first voltage across the first diode, the first voltage associated with the first current, to transmit a second current through the first diode, and to determine a second voltage across the first diode, the second voltage associated with the second current. The device may be further adapted to transmit a third current through the first diode, to determine a third voltage across the first diode, the third voltage associated with the third current, and to determine a temperature of the first diode based at least in part on the first voltage, the second voltage and the third voltage.

Method and apparatus to determine integrated circuit temperature

A client/server network system is disclosed for cyclic multicasting of an image file from a central data provider (server) to one or more remote client machines (workstations) over a computer network with minimum network transmission while allowing any number of client machines (workstations) to download the image file at any moment in time without the need to synchronize with the central server's transmission. The network system includes a computer network; a plurality of remote client machines on the computer network; and a central server for providing a cyclic multicasting of an image file to one or more client machines over the computer network concurrently through the use of different transmission cycles of a single cyclic multicast session. An image file is asynchronously transferred from the central server to one or more remote client machines concurrently over a computer network through the use of different transmission cycles during a single cyclic multicast session so as to keep the network transmission and network bandwidth to a minimum.
