Description

Block Diagram Memory Overview IZE4442 Figure 1 Memory Overview The IZE4442 consists of 256 x 8 bit EEPROM main memory and a 32-bit protection memory with PROM functionality.The main memory is erased and written byte by byte.When erased, all 8 bits of a data byte are set to logical one.When written, the information in the individual EEPROM cells is, according to the input data, altered bit by bit to logical zeros, (logical AND between the old and the new data in the EEPROM).Normally a data
