IC memory card comprising an EEPROM with data and address buffering for controlling the writing/reading of data to EEPROM

摘要

An IC memory card connectable to a host has a storage implemented as an EEPROM, and a control circuit for controlling the storage to write data transferred from the host to the memory card in the storage. The control circuit has latches for temporarily holding input data and an address representative of a particular storage location of the storage for storing the data which are transferred from the host, a clock input terminal for receiving from the host a first clock for causing the latches to hold the data, and a clock generator for generating a second clock for writing the data in the storage.
