A digital computer store with very short read time

摘要: The paper describes the principles of operation and construction storage units with a very short access time for reading. One form store which has been constructed capacity 200 000 bits permanent information another built 100 bits, whole contents may be changed in under one minute. technique employed permits large stores at low cost. Each digit cell is formed, basically, by two sets windings primary secondary transformer binary states are determined presence or absence piece linear ferrite material coupling windings. largely physical size speed associated circuits; millimicrosec typical.
