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.

主权项

1. An apparatus comprising:
a first memory device comprising:
a first address node to receive information; anda chip select node to receive a first chip select signal; a second memory device, coupled in a mirrored configuration with the first memory device, the second memory device comprising:
a second address node coupled to the first address node of the first memory device, the second address node to also receive the information; anda chip select node to receive a second chip select signal; and a memory controller to provide a single chip select signal as the first and second chip select signals in a first mode of operation and to provide separate chip select signals as the first and second chip select signals in a second mode of operation.
