APPARATUSES AND METHODS INCLUDING SELECTIVELY PROVIDING A SINGLE OR SEPARATE CHIP SELECT SIGNALS

摘要

Apparatus and methods are disclosed herein, including those that operate to initialize registers of a first memory device and a second memory device of a single-rank memory module by providing separate chip select signals to separately select a first memory device and a second memory device. A method may further include, subsequent to sensing that the initializing is completed, for example, providing a single chip select signal to simultaneously select the first memory device and the second memory device.

1. A method of operating a memory apparatus, the method comprising:
providing, during a first mode of operation, an active first signal to a chip select node of a first memory device to select the first memory device; providing, during the first mode of operation, an active second signal to a chip select node of a second memory device to select the second device, wherein the second memory device is coupled to the first memory device in a mirrored configuration; and providing, during a second mode of operation, an active single signal to the chip select node of the first memory device and to the chip select node of the second memory device to simultaneously select the first and second memory devices.
