A write occurs during the overlap(tWP ) of low CS and low WE. A write begins when CS goes low and WE goes low with asserting UB or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest transition when CS goes high and WE goes high. The tWP is measured from the beginning of write to the end of write. 2. t CW is measured from the CS going low to end of write. 3. t A S is measured from the address valid to the beginning of write. 4. t WR is measured from the end or write to the address change. tWR applied in case a write ends as CS or WE going high. 8 EM611FV16 Series merging Memory & Logic Solutions Inc.
