Write with Auto Precharge
During a write cycle, the auto precharge starts at the timing that is equal to the value of t
DPL
(min.) after the last data word
input to the device.
In summary, the auto precharge cycle begins relative to a reference clock that indicates the last data word is valid. In the
table below, minus means clocks before the reference; plus means clocks after the reference.
