A technique is described whereby an electronically erasable programmable read-only memory (EEPROM) array and control circuitry is incorporated into the circuitry of the IBM Personal Computer (PC), so as to provide non-volatile electronic storage of information in place of or in addition to various types of storage, such as diskettes or magnetic tape. With the advent of low cost EEPROMs, such as the 256K or 512K byte EEPROM, control circuitry and the implementation of the EEPROM, as described herein, enables the personal computer to store and erase data electronically. By incorporating either 256K or 512K byte EEPROMs, a total of up to 2.04 megabytes of non-volatile storage is obtained without increasing power supply requirements.
