CMOS Memory Complementary Metal Oxide Semiconductor (CMOS) is a transistor that combines both positive and negative channel in the same circuit‚ and consume lower amounts of power when compare with single polarity devices. In 1963 C. T. Sah and Frank Wanlass prove that combining both channels in a circuit drew close to zero power in standby mode. RCA laboratories first produce CMOS technology for aerospace and commercial applications. The first static RAM was introduced in 1968 with

same risk if it is not utilized frequently‚ becoming weaker over the time provoking a failure of memory retrieval. Regardless of whether we have been able to encode and store our memories correctly‚ our brain may fail to retrieve it. One of the reasons why this happens is cue-dependent forgetting‚ which means that we do not have enough connectors or clues to help us identify information stored in our memory. Additionally‚ we have what is called state-dependent learning‚ where the only way to remember
