ACCESS OPERATION STATUS SIGNALING FOR MEMORY SYSTEMS

Abstract:

Techniques for access operation status signaling for memory systems are described. In some examples, a memory system may respond to access commands from a host system by performing access operations such as read or write operations. In accordance with examples as disclosed herein, a system may be configured to support access operation status signaling between a host system and a memory system, which may improve the ability of the system to adapt to various access scenarios, including when access operation completion is delayed. For example, when a memory system is performing an error recovery or media management operation, the memory system may indicate that the error recovery or media management operation is being performed or is otherwise ongoing. Such status signaling may indicate that the memory system is actively performing operations, which may be used to inhibit a reset or reinitialization by a host system.
