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 288-bit capacity. In the first integrated microprocessor with CMOS technology only had 4bit and in 1972 an 8bit version was released. In 1975 RCA produces the COSMAC 1802 microprocessor to be use in Chrysler automobile engine control units (ECU). Low cost versions of the 8bit integrate chip make way to personal computers and video game consoles. The CMOS technology kept evolving acquiring more capacity at the same time that the chip that was embedded in became smaller. The CMOS technology power requirement has reduced with every generation chip. Until 2008 most CMOS memory required a small amount of constant power. In that year Virage Logic Corp. released an embedded multi-time programmable non-volatile memory emPROMP that can storage 1Mbit. Modern computers use flash ROM to store the CMOS settings, and do not require an external battery. The Norwegian developer of printable memory and California’s Xerox PARC announced the development a working prototype of the world’s first printed non-volatile memory CMOS chip. The combination of polymer-base memory with transistor technology resulted in CMOS chips that can be printed in a roll. These memory chips are rewritable and do not require external power source. These memory chips can be produce at such small size that in a near future could be integrated in to anything from price tags to groceries packaging information labels. This is the future of CMOS memory today.
