US 12,769,460 B2 · Two-stage emergency data storing operation

Abstract

Implementations described herein relate to a two-stage emergency data storing operation. In some implementations, a memory device may detect a power loss notification signal that indicates a power loss condition of the memory device. The memory device may read a mode register bit of the memory device that indicates to perform a data storing operation that includes a first data storing stage and a second data storing stage. The first data storing stage may include storing data associated with the memory device prior to the memory device experiencing a power loss, and the second data storing stage may include storing data and metadata associated with the memory device prior to the memory device experiencing the power loss. The memory device may initiate the data storing operation and may selectively acknowledge the power loss condition based on completing the first data storing stage or the second data storing stage.

Dependent claims

A memory device, comprising:

one or more components configured to:
read a mode register bit of the memory device,
wherein a first state of the mode register bit indicates to perform a first data storing operation that includes a first stage and a second stage,
wherein a second state of the mode register bit indicates to perform a second data storing operation that includes only one of the first stage or the second stage, and
wherein the first stage includes storing data prior to the memory device experiencing a power loss, and the second stage includes storing data and metadata prior to the memory device experiencing the power loss;
and
initiate the first data storing operation or the second data storing operation based on the mode register bit.
