Data inputs/outputs are multiplexed on the same pins.
Isolated power supply for the output buffers to provide improved noise immunity.
Data input/output are multiplexed on the same pin.
This pin is recommended to be left no connection on the device.
Ground for the input buffers and core logic.
Makes data output Hi-Z, tSHZ after the clock and masks the output.
Blocks data input when DQM active.
Row/column addresses are multiplexed on the same pins.
Row address : RA0 - RA10, Column address : CA0 - CA7
Masks system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior to new command.
Disables input buffers for power down mode.
Active on the positive going edge to sample all inputs.
This pin is recommended to be left no connection on the device.
