Title: Auxiliary supply backup for digital memories - with accumulator supply which cuts in when main supply fails and prevents contents read out if voltage falls below preset value
Inventor: SCHWARTZ GUENTER DIPL ING
IPC: G01R31/36
Filed: 1976-03-06
Abstract: An auxiliary accumulator supply provides back up for memories in a data processing system in the event of a mains power loss, and operates to inhibit read out when the standby voltage falls below a predetermined level. An operating voltage discriminator (10) generates an output and provides that the supply voltage is above a safe level (4.5V). After delaying (14) the signal allows the supply to be gated (5) over a diode ( ) to the memory (1). In this condition the accumulator (7) is being charged (8) and the output inhibited (6). A gate (15) controls the data processing cycle and a 'D' type flip-flop allows read-out to be made dependent upon a signal from a discriminator (12). When the supply voltage fails the accumulator supplies the memory and the cycle is inhibited (15). If the auxiliary voltage falls below a preset value the 'D' flip-flop inhibits read out.
