Data Mask
The SDRAM has a Data Mask function that can be used in conjunction with data read and write cycles. When the Data Mask is
activated (DQM high) during a write cycle, the write operation is prohibited immediately (zero clock latency). If the Data Mask is
activated during a read cycle, the data outputs are disabled and become high impedance after a two-clock delay, independent
of CAS latency.
No Operation Command
The No Operation Command should be used in cases when the SDRAM is in an idle or a wait state. The purpose of the No
Operation Command is to prevent the SDRAM from registering any unwanted commands between operations. A No Operation
Command is registered when CS is low with RAS, CAS, and WE held high at the rising edge of the clock. A No Operation Com-
mand will not terminate a previous operation that is still executing, such as a burst read or write cycle.
Deselect Command
The Deselect Command performs the same function as a No Operation Command. Deselect Command occurs when CS is
brought high, the RAS, CAS, and WE signals become don’t cares.
