Fetches all inputs at the "H" edge.

Disables or enables device operation by asserting or deactivating all inputs except CLK, CKE, DQM0 - 3.

Masks system clock to deactivate the subsequent CLK operation.

If CKE is deactivated, system clock will be masked so that the subsequent CLK operation is

deactivated. CKE should be asserted at least one cycle prior to a new command.

Row & column multiplexed.

Row address: RA0 - RA10

Column address: CA0 - CA7

Bank Access pins. These pins are dedicated to select one of 4 banks.

Functionality depends on the combination. For details, see the function truth table.
