Note:
The mode register set stores the data for controlling the operating modes of the memory.
It programs the RLDRAM configuration, burst length, test mode, and I/O options.
During an MRS command, the address inputs A0–A17 are sampled and stored in the
mode register. After issuing a valid MRS command,
command can be issued to the RLDRAM. This statement does not apply to the consecu-
tive MRS commands needed for internal logic reset during the initialization routine. The
MRS command can only be issued when all banks are idle and no other operation is in
progress.
