CKESTR – Strength Control Register for CKE Signal Group
Address Offset:
31h
Default Value:
00h
Access:
Read Only, Read/Write
Size:
8 bits
This register controls the drive strength of the I/O buffers for the CKE signal group. This group has two
possible loadings depending on the width of SDRAM devices used in each Row of memory (x8 or x16).
The proper strength can be independently programmed for each configuration. The actual strength used
for each signal is determined by the DRAM Width Register (offset 2Ch).
