Abstract

1520573 Data storage CASIO COMPUTER CO Ltd 23 Feb 1976 [26 Feb 1975] 07081/76 Heading G4A Data from a keyboard 14 is stored in a semiconductor memory in a removable unit 10 which is transferred to a processing unit. The removable unit 10 contains a battery which may be recharged each time the unit is engaged with a keyboard unit or a processing unit. The semiconductor memory may be formed by MOS transistors and may be a continuously circulating shift register (31, 34, Fig. 3, not shown)- there being associated circuitry for detecting the first and last stored bits.
