Read operation using compressed memory

A non-transitory computer-readable medium storing code comprising instructions which, when executed by a processor of an electronic device, cause the electronic device to:

• receive a command to access data stored in a non-volatile memory device;
• determine, by a host system coupled with the non-volatile memory device and a volatile memory device, whether a compressed copy of the data is additionally stored in the volatile memory device, the compressed copy of data associated with a logical block address (LBA) of the non-volatile memory device based at least in part on receiving the command;
• transmit, from the host system to the volatile memory device coupled with the host system, a read command that includes logical address of the volatile memory device that is associated with the LBA of data stored in the non-volatile memory device coupled with the host system based at least in part on determining whether the compressed copy of the data is stored in the volatile memory device;
• and
• receive, at the host system from the volatile memory device, the compressed copy associated with the LBA stored in the volatile memory device of the data stored in the non-volatile memory device.

A method performed by a host system coupled with a non-volatile memory device and a volatile memory device, comprising:

• receiving a command to access data stored in the non-volatile memory device;
• determining whether a compressed copy of the data is additionally stored in the volatile memory device, the compressed copy of data associated with a logical block address (LBA) of the non-volatile memory device based at least in part on receiving the command;
• transmitting, to the volatile memory device coupled with the host system, a read command that includes a logical address of the volatile memory device that is associated with the LBA of data stored in the non-volatile memory device coupled with the host system based at least in part on determining whether the compressed copy of the data is stored in the volatile memory device;
• and
• receiving, from the volatile memory device, the compressed copy associated with the LBA stored in the volatile memory device of the data stored in the non-volatile memory device.
