Tunnel diode storage system with non-destructive read-out

A brief survey of some tunnel diode storage systems is presented and a description of a particular system with a non-destructive read-out feature is given. The design of this system is discussed in some detail, and an assessment of the operating margins is included. In a unit of 128 words of 24 digits per word a read access time of 150 m¿s is indicated with a read cycle time of 250 m¿s. The write cycle time is 330 m¿s.
