US 2026/0277474 A1 · MEMORY SYSTEMS, METHODS OF OPERATING THE SAME, AND STORAGE MEDIUMS

Abstract

Examples of the present application provide memory systems, methods of operating thereof, and storage mediums. An example memory system includes at least one memory device and a memory controller; the memory controller is coupled with both a host and the memory device and includes a write buffer and a control section coupled with the write buffer; the control section is configured to: in response to upcoming execution of an erase event of a block in the memory device, configure a portion of an idle storage space of the memory controller as a newly-added storage space of the write buffer; write data received from the host to the newly-added storage space of the write buffer in response to execution of the erase event; and release the newly-added storage space of the write buffer in response to completion of the erase event.

Dependent claims

A memory system, comprising:

a memory device comprising blocks;
and
a memory controller coupled to the memory device and configured to:
receive a write command from a host;
in response to determining that a first block of the blocks requires erasure to make the first block available for writing, obtain first data having a first data amount from the host;
write the first data having the first data amount into the first block;
in response to completion of erasure of the first block, obtain second data having a second data amount from the host, wherein the first data amount is greater than the second data amount;
and
write the second data having the second data amount into the first block.
