Intelligent 104-Bit EEPROM Counter for > 20000 Units with Security Logic

Integral Corp. 

IZ4406

After the control flag has been written, everything is readable and only area III can be

programmed, but with the following changes:

- The transport code and the error counter are no longer activated.

- The area of the former transport code and the error counter can be erased byte by byte

with carry.

- The entire area III can be written bit by bit

NB: When the control flag is written, the counter stage below it (the error counter) can be

erased at the same time (see “Erasing Memory Byte with Carry”).
