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 read quickly 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 enters a ...

Figure 8: Software Access PAR Functionality No Deep Power-Down Operation Deep power-down (DPD) operation disables all refresh-related activity. This mode is used when the system does not require the storage provided by the PSRAM device. Any stored data will become ...

Page 14

Configuration Register Operation The configuration register (CR) defines how the PSRAM device performs a transparent self refresh. Altering the refresh parameters can dramatically reduce current consump- tion during standby mode. Page mode control is embedded in the CR. This register ...

Page 15

Software Access to the Configuration Register The contents of the CR can be read or modified using a software access sequence. The nature of this access mechanism can potentially eliminate the need for the ZZ# ball. If the software-access mechanism ...
