Integrated circuit memory card for write in/read out capability having plurality of latching means for expandable addressing using counting means for enabling latches thereof |
摘要 |
An IC memory card for storing picture data, character data or similar data. The memory card has an input/output section connectable to a host, a storage implemented by a semiconductor memory, and a controller for writing or reading data out of the storage. The input/output section has a data terminal for receiving an address signal and a data signal each being made up of a plurality of blocks continuously, an address/data discrimination terminal for receiving a bilevel signal for discriminating the address signal and data signal fed to the data terminal from each other, a read/write discrimination terminal for receiving a bilevel signal for discriminating the read-out and write-in of data from each other, and a bus clock input terminal for receiving a bus clock synchronous to each block of the address signal or each block of the data signal.
