Intel’s 2-Mbit Flash Memory Family is an extension of the Boot Block Architecture which includes block-selective erasure, automated write and erase operations and standard microprocessor interface. The 2 Mbit Flash Memory Family enhances the Boot Block Architecture by adding more density and blocks, x8/x16 input/output control, very high speed, low power, an industry standard ROM compatible pinout. The 2-Mbit flash family allows for an easy upgrade to Intel’s 4-Mbit Boot Block Flash Memory Family.
