Abstract
An EEPROM (1) is set to write mode when a program command to commence rewriting of data in region B in the EEPROM (1) is read out from region A. A CPU (2) then writes data specified by a latch (6) at an address in region B specified by a latch (4). In compliance with an inhibit signal INH, the CPU (2) now disregards the effects of the undefined output from the EEPROM (1) terminal DOUT.
