8.6 Extended Mode Register Description
The Extended Mode Register designates the operation condition while SDRAM is in Self Refresh Mode and selects the
output driver strength as full, 1/2, 1/4, or 1/8 strength. The register is divided into two fields; (1) Partial Array Self Refresh
field selects how much banks or which part of a bank need to be refreshed during Self Refresh. (2) Driver Strength selected
bit to control the size of output buffer. The initial value of the Extended Mode Register after power-up is Full Driver
Strength, and all banks are refreshed during Self Refresh Mode.
