Abstract
A memory management method, a memory storage device, and a memory control circuit unit are provided. The method includes establishing a connection between the memory storage device and a host system; receiving a first request from the host system via the connection; detecting a status of the memory storage device in a time range according to the first request; and determining whether to use a memory in the host system according to the status.
Claims28
A memory management method for a memory storage device, the memory management method comprising:
- establishing a connection between the memory storage device and a host system;
- receiving a first request from the host system via the connection;
- detecting a status of the memory storage device within a time range according to the first request;
- and
- determining whether to use a memory in the host system according to the status.
A memory storage device, comprising:
- a connection interface unit, used to couple to a host system;
- a rewritable non-volatile memory module;
- and
- a memory control circuit unit, coupled to the connection interface unit and the rewritable non-volatile memory module,
- wherein the memory control circuit unit is used to:
- establish a connection between the memory storage device and the host system;
- receive a first request from the host system via the connection;
- detect a status of the memory storage device within a time range according to the first request;
- and
- determine whether to use a memory in the host system according to the status.
A memory control circuit unit for controlling a memory storage device, wherein the memory storage device comprises a rewritable non-volatile memory module, the memory control circuit unit comprising:
- a host interface, used to couple to a host system;
- a memory interface, used to couple to the rewritable non-volatile memory module;
- and
- a memory management circuit, coupled to the host interface and the memory interface,
- wherein the memory management circuit is used to:
- establish a connection between the memory storage device and the host system;

- detect a status of the memory storage device within a time range according to the first request;
- and
- determine whether to use a memory in the host system according to the status.
A memory management method for a memory storage device, the memory management method comprising:
- establishing a connection between the memory storage device and a host system;
- receiving a first request from the host system via the connection;
- detecting a status of the memory storage device within a time range according to the first request;
- and
- determining whether to enable the memory storage device to enter a low power consumption mode according to the status.
A memory storage device, comprising:
- a connection interface unit, used to couple to a host system;
- a rewritable non-volatile memory module;
- and
- a memory control circuit unit, coupled to the connection interface unit and the rewritable non-volatile memory module,
- wherein the memory control circuit unit is used to:
- establish a connection between the memory storage device and the host system;
- receive a first request from the host system via the connection;
- detect a status of the memory storage device within a time range according to the first request;
- and
- determine whether to enable the memory storage device to enter a low power consumption mode according to the status.
A memory control circuit unit for controlling a memory storage device, wherein the memory storage device comprises a rewritable non-volatile memory module, the memory control circuit unit comprising:

- receive a first request from the host system via the connection;
- detect a status of the memory storage device within a time range according to the first request;
- and
- determine whether to enable the memory storage device to enter a low power consumption mode according to the status.
A memory storage device, comprising:
- a connection interface unit, used to couple to a host system;
- a rewritable non-volatile memory module;
- and
- a memory control circuit unit, coupled to the connection interface unit and the rewritable non-volatile memory module,
- wherein the memory control circuit unit is used to:
- establish a connection between the memory storage device and the host system;
- receive a first request from the host system via the connection;
- detect whether at least one event occurs within a time range according to the first request, wherein the at least one event affects an execution effect of an operation instructed by the first request;
- and
- determine whether to execute the operation according to a detection result.
