US 2026/0010316 A1 · MEMORY MANAGEMENT DURING SUSPEND AND RESUME OPERATIONS

Abstract

Methods, systems, and devices for memory management during suspend and resume operations are described. In some examples, a memory system may receive an indication of a range of addresses for storing an image of a host system. In some cases, the host system may indicate a logical unit that is dedicated for suspend and resume operations. In some other cases, the memory system may receive a command indicating that the host system is in a suspend state or a resume state for a duration. In response to the command, the memory system may track accesses to the non-volatile media during the duration to determine the range of addresses associated with the image of the host system. Additionally, the memory system may implement one or more write optimizations, read optimizations, or both, to further improve the performance of the memory system during suspend and resume operations.

Dependent claims

A memory system, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the memory system to:
receive an indication of a range of addresses for storing a memory image of a host device, the range of addresses of an address space of the memory system;
receive data from the host device associated with the range of addresses;
and
write the data to one or more memory arrays of the memory system according to at least one parameter associated with storing the memory image.
