US 12,602,170 B2 · Write buffer flush techniques

Abstract

Methods, systems, and devices for write buffer flush techniques are described. A memory system may be triggered to flush (e.g., transfer, write) data from a volatile memory device to a non-volatile memory device of the memory system. The memory system may support flushing data to blocks including single level cells (SLCs) or blocks including multiple-level memory cells. The memory system may determine whether a quantity of the data to be flushed satisfies a threshold quantity of data. If the quantity of data fails to satisfy the threshold quantity of data, the memory system may flush the data to a block including SLCs, which may be referred to as a small chunk SLC cursor. The SLC cursor may temporarily store the flushed data, such as at least until the threshold quantity of data is satisfied in the volatile memory device and/or to data recovery in case of a power loss event.

Dependent claims

An apparatus, comprising:

a non-volatile memory device;
a volatile memory device;
and
a controller coupled with the non-volatile memory device and the volatile memory device, wherein the controller is configured to cause the apparatus to:
receive one or more commands to write data to the apparatus, a command of the one or more commands triggering a transfer of the data from the volatile memory device to the non-volatile memory device;
determine whether a quantity of the data to transfer to the non-volatile memory device satisfies a threshold associated with writing the data to a first block of the apparatus that comprises multiple-level memory cells;
and
write, based at least in part on the quantity of data failing to satisfy the threshold, the data and an indication of one or more physical addresses of the first block to a second block of the apparatus that comprises single-level memory cells, wherein the one or more physical addresses for which the indication is written to the second block correspond to one or more pages of the first block to which the data is to subsequently be written.

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 one or more commands to write data to a memory system, a command of the one or more commands triggering a transfer of the data from a volatile memory device of the memory system to a non-volatile memory device of the memory system;
determine whether a quantity of the data to transfer to the non-volatile memory device satisfies a threshold associated with writing the data to a first block of the memory system that comprises multiple-level memory cells;
and
write, based at least in part on the quantity of data failing to satisfy the threshold, the data and an indication of one or more physical addresses of the first block to a second block of the electronic device that comprises single-level memory cells, wherein the one or more physical addresses for which the indication is written to the second block correspond to one or more pages of the first block to which the data is to be subsequently written.
