Semiconductor memory device including a controller for controlling power and electronic device including the semiconductor memory device
First Claim
1. A semiconductor memory device comprising:
- a memory including a plurality of units; and
a controller,wherein, under control of the controller, a power for an operation of the memory is independently supplied to each of the plurality of units or is independently blocked with respect to each of the plurality of units,wherein the power is additionally supplied to at least a part of the plurality of units to which the power is not supplied, under control of the controller, andwherein the controller performs initialization on the at least a part of the plurality of units.

Abstract
A semiconductor memory device includes a memory including a plurality of units, and a controller. Under control of the controller, a power for an operation of the memory is independently supplied to each of the plurality of units or is independently blocked with respect to each of the plurality of units. Each of the plurality of units may be one of a package, die, or chip. A supply of the power to at least a part of the plurality of units, to which the power is supplied, may be blocked under control of the controller. Accordingly, unnecessary power consumption may be prevented. Furthermore, power may be additionally supplied to at least a part of the plurality of units to which the power is not supplied, under control of the controller, and these units may be initialized.

11. An electronic device comprising:
-
a host; and a semiconductor memory device, wherein the semiconductor memory device includes; a memory including a plurality of units; and a controller, wherein, under control of the controller, a power for an operation of the memory is independently supplied to each of the plurality of units or is independently blocked with respect to each of the plurality of units, wherein the host is an application processor, wherein the semiconductor memory device is configured to load an application to be executed in the host or to temporarily store data needed to drive the application, and wherein, when a capacity of an area in the memory used to drive the application is smaller than a capacity of an area in the memory to which the power is supplied, a supply of the power to at least an unused part of the plurality of units of the area in the memory to which the power is supplied is blocked under control of the controller. - View Dependent Claims (12, 13, 14, 15, 16, 17)
