WebThe WRITE operation is very similar to the READ. The main difference is that the R/W line must be set for writing before the CAS line is asserted. Then the direction of data transfer is to write data placed on the bi-directional DIO lines into the memory during CAS assertion. The initial row refresh and the post-write recovery are the same as the WebApr 10, 2024 · PIT 7 UNIT 5 The sense amplifier specifies whether the cell contains a logic 1 or logic 2 by comparing the capacitor voltage to a reference value. The reading of the cell results in discharging of the capacitor, which must be restored to complete the operation.
