Abstract
An EPROM includes an on chip circuitry for selecting an alternative chapter mode addressing scheme. By utilizing the chapter addressing mode, a plurality of devices can be coupled in parallel, wherein each device is treated as a chapter of the total memory capacity. Hard latches are used to store a designated code and soft latches are used to latch in chapter addresses from data lines. A chapter is evaluated if values stored in the hard latch match the values inputted to the soft latch.
