I<2>C bus-compatible, serial EEPROM device (10) is used in applications involving storage and serial transmission of configuration and control information for an associated intelligent peripheral device communicating on a bus to a host device. The EEPROM device (10) has a memory array (20) storing data representing the configuration and control information. Two modes of data transmission are supported by the EEPROM device (10), and are alternately and selectively established according to whether data stored in EEPROM array is to be accessed read only or read/write. The arrangement allows intelligent interaction between the host and the peripheral device. Multiplexer (35) selectively connects the input clock, comprising either the usual input clock line to the bus or a separate clock line, for clocking the different modes according to a predetermined logic level transition on one of the two clock lines.
