Random access memory arrangements

摘要: A random access memory arrangement for reading data out of and into a asynchronously, example, to effect time base correction digital television signal, comprises having common read write terminals, an input circuit supplying said terminals writing in the memory, first output latch connected second circuit, means control signals enable therein at given addresses synchronism with pulses pulse from signal being asynchronous hold supply supplied immediately prior each pulse, pass therethrough all other times, it by beginning until next succeeding so held arrangement.
