Page Mode READ Operation Page mode is a performance-enhancing extension to the legacy asynchronous READ operation. In page-mode-capable products, an initial asynchronous read access is performed, then adjacent addresses can be quickly read by simply changing the low- order address. ...

Low-Power Operation Standby Mode Operation During standby, the device current consumption is reduced to the level necessary to perform the DRAM REFRESH operation on the full array. Standby operation occurs when CE# and ZZ# are HIGH. The device will enter ...
