256Mb (4-Meg X 16-Bit X 4-Banks) SDRAM
03.25.04 Rev 3
Initialization sequence: When 200ms or more has past after the power up sequence, all banks must be
precharged using the precharge command (PALL). After t
RP delay, set 8 or more auto refresh commands
(REF). Set the mode register set command (MRS) to initialize the mode register. It is recommended that by
keeping DQMU/DQML and CKE High, the output buffer becomes High-Z during initialization sequence, to
avoid DQ bus contention on a memory system formed with a number of devices.
