A write occurs during the overlap(tWP ) of low CS1, a high CS2 and low WE. A write begins at the latest transition among CS1 goes low, CS2 goes high and WE goes low. A write ends at the earliest transition when CS1 goes high, CS2 goes hagh and WE goes high. The t WP is measured from the beginning of write to the end of write. 2. t CW is measured from the CS1 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 CS1 or WE going high. 8 EM610FV8 Series merging Memory & Logic Solutions Inc.
