Abstract: An electronic circuit (200) for use with an accessing circuit (110) that supplies a given address and a partial write data portion and also has dummy cycles. The electronic circuit (200) includes a memory circuit (230) accessible at addresses, an address buffer (410), a data buffer (440) coupled to the memory circuit (230), and a control circuit (246) operable in the dummy cycles to read data from the memory circuit (230) to the data buffer (440) from a next address location in the memory circuit (230) and to store that next address in the address buffer (410). The electronic circuit further includes a multiplexer (430), a comparing circuit (420) responsive to the given address and a stored address in the address buffer (410), to operate the multiplexer (430) to pass data from the data buffer (440) or to pass data from the memory circuit (230) instead; and a mixer circuit (450) operable to put the partial write data portion into the data taken from the selected one of the data buffer (440) or memory circuit (230). Other circuits, devices, systems, processes of operation and processes of manufacture are also disclosed.
