Abstract:
1. An electronic circuit for use with an accessing circuit that supplies a given address and a partial write data portion and also has dummy cycles, the electronic circuit comprising: a memory circuit accessible at addresses; an address buffer; a data buffer coupled to said memory circuit; a control circuit operable in the dummy cycles to read data from said memory circuit to said data buffer from a next address location in said memory circuit and to store that next address in said address buffer; a multiplexer; a comparing circuit responsive to the given address and a stored address in said address buffer, to operate said multiplexer to pass data from said data buffer or to pass data from said memory circuit instead; and a mixer circuit operable to put the partial write data portion into the data taken from the selected one of said data buffer or memory circuit.
