Managing write command execution during a power failure in a memory sub-system

Abstract

A system includes a memory device and a processing device, operatively coupled with the memory device, to perform operations including: detecting an asynchronous power loss event at the memory device; receiving, from a host system, a memory access command; determining that a size of the memory access command satisfies a threshold criterion, wherein the threshold criterion corresponds to an atomic write unit size; responsive to determining that the size of the memory access command satisfies the threshold criterion, executing the memory access command using a hardware component of the memory device; and responsive to executing the memory access command, notifying the host system of completion of execution of the memory access command.
