Abstract
An interface circuit for coupling a data handling unit with a memory unit having control inputs, an address signal input, a data signal input, and a data signal output is described. The interface circuit comprises an address buffer having an input and an output, said input receiving an address signal from said data handling unit, a first multiplexer which couples said memory unit with either said output of said address buffer or with said address signal, a data buffer having an input and an output, said input receiving a data signal from said data handling unit and said output being coupled with said memory data input, a second multiplexer for selecting either said memory data signal output or said data buffer output, and a comparator for comparing said address signal with the signal from said address buffer output, generating a control signal which controls said second multiplexer.
