Method and Computing Device for Fast Erase of Swap Memory

摘要

The following embodiments generally relate to the use of a “swap area” in a non-volatile memory as an extension to volatile memory in a computing device. These embodiments include techniques to use both volatile memory and non-volatile swap memory to pre-load a plurality of applications, to control the bandwidth of swap operations, to encrypt data stored in the swap area, and to perform a fast clean-up of the swap area.

主权项

1. A method for fast erase of a swap area in a non-volatile memory, the method comprising:
performing the following in a controller of a storage module in communication with a processor of a computing device, wherein the storage module comprises a non-volatile memory having a swap area with a plurality of blocks storing data that was swapped out of a volatile memory of the computing device:
receiving a multi-block erase command from the processor of the computing device to erase the plurality of blocks in the swap area in non-volatile memory; andin response to receiving the command, simultaneously erasing all of the plurality of blocks.
