US 2026/0267790 A1 · MEMORY SYSTEM AND METHOD

Abstract

A memory system includes a nonvolatile memory including a plurality of storage regions, each of which includes a plurality of memory cells, and a controller electrically connected to the nonvolatile memory. The controller is configured to: in response to an inquiry command received from a host, the inquiry command including at least a first logical address, determine whether internal movement of first data corresponding to the first logical address is scheduled to be started within a predetermined amount of time from a receipt time of the inquiry command, and in response to determining that the internal movement of the first data is scheduled to be started within the predetermined amount of time from the receipt time of the inquiry command, transmit schedule information to the host, the schedule information indicating when the internal movement of the first data will be started.

Dependent claims

A memory system comprising:

a nonvolatile memory including a plurality of storage regions, each of which includes a plurality of memory cells each configured to store data in accordance with a threshold voltage thereof;
and
a controller electrically connected to the nonvolatile memory and configured to:
in response to an inquiry command received from a host, the inquiry command including at least a first logical address, determine whether internal movement of first data corresponding to the first logical address is scheduled to be started within a predetermined amount of time from a receipt time of the inquiry command;
and
in response to determining that the internal movement of the first data is scheduled to be started within the predetermined amount of time from the receipt time of the inquiry command, transmit schedule information to the host, the schedule information indicating when the internal movement of the first data will be started.

3 more elements

A method of notifying a host of scheduled internal movements of data within a memory system that includes a nonvolatile memory including a plurality of storage regions, each of which includes a plurality of memory cells each configured to store data in accordance with a threshold voltage thereof, said method comprising:

in response to an inquiry command received from the host, the inquiry command including at least a first logical address, determining that internal movement of first data corresponding to the first logical address is scheduled to be started within a predetermined amount of time from a receipt time of the inquiry command;
and
in response to determining that the internal movement of the first data is scheduled to be started within the predetermined amount of time from the receipt time of the inquiry command, transmitting schedule information to the host, the schedule information indicating when the internal movement of the first data will be started.
