Write Access

low and the latch becomes transparent. This allows the address to be propagated to the memory array. The address is

stable at the rising edge of the AVD signal. The AVD signal goes high at point B in which the address latch is completed.

At this point, the second stage of the write process is entered. Data is input to the multiplexed address/data bus. The WE

signal is set low and control signal UB and LB are set according to the access.
