Extended Mode Register 2 (EMR2)

256MbDDR2.pdf - Rev. M 7/09 EN
Notes:
The extended mode register 2 (EMR2) controls functions beyond those controlled by
the mode register. Currently all bits in EMR2 are reserved, except for E7, which is used
in commercial or high-temperature operations, as shown in Figure 39. The EMR2 is pro-
grammed via the LM command and will retain the stored information until it is program-
med again or until the device loses power. Reprogramming the EMR will not alter the
contents of the memory array, provided it is performed correctly.
Bit E7 (A7) must be programmed as “1” to provide a faster refresh rate on IT and AT
devices if T
EMR2 must be loaded when all banks are idle and no bursts are in progress, and the
controller must wait the specified time
tion. Violating either of these requirements could result in an unspecified operation.
