Abstract: An apparatus includes a storage resource to store data. The data can be accessible by a host computer system. The apparatus includes a set of dynamically powered volatile memory devices that are configured to store mapping information. The mapping information maps logical addresses of received access requests to corresponding physical addresses of the storage resource to which the access requests pertain. In accordance with received mode setting information, the controller logic adaptively controls power settings of the volatile memory devices storing the mapping information. If an abundance of power such as 120 VAC power is available, more of volatile memory devices can be powered to store a greater portion of the mapping information. If only battery power is available, fewer than all of the volatile memory devices can be powered to store a smaller portion of the mapping information.

Abstract: Methods and apparatus related to generating random numbers utilizing the entropic nature of NAND flash memory medium are described. In one embodiment, a data pattern is written to a portion of a non-volatile memory device and is subsequently read multiple times. Based on the read operations, at least one bit is marked for random number generation based at least partially on comparison of a number of flips by the at least one bit and a threshold value. Other embodiments are also disclosed and claimed.
