DESCRIPTION
A write cycle is similar to a read cycle except WE is set to a Low state and OE is a “H” or “L” signal. A write cycle can be
implemented in either of three ways–early write, delayed write, or read-modify-write. During all write cycles, timing param-

satisfied, data on the DQ pins are
latched with the falling edge of CAS and written into memory.
