HMOS is Harmonic Metal oxide Semiconductor.

In the early to mid 1980s, CMOS was still quite slow and used mostly for the 4000 series, Static RAMs, and low-power ASICs (such as watch and calculator ICs). Advanced processes for depletion-load nMOS, such as Intel's family of scaled HMOS (High density, short channel MOS) processes were therefore used for most microprocessors, certain types of memories, and many support and peripheral ICs. The first nMOS process called HMOS (late 1976) was originally used for Intel's then central static RAM products. Although primarily intended for fast SRAM, it was soon employed also for faster and/or less power hungry versions of the 8085, 8086, and other chips. HMOS was also licensed to other manufacturers, such as Motorola, which used it to manufacture the Motorola 68000 series, for instance. According to Intel, HMOS-II (1979) provided twice the density and four times the speed/power product over other typical contemporary depletion-load nMOS processes. HMOS, HMOS II, HMOS III, and HMOS IV were together used for many different kinds of processors; the 8085, 8048, 8051, 8086, 80186, 80286, and many others, but also for several generations of the same basic design, see datasheets.

High-Level Data Link Control (HDLC) is a bit-oriented code-transparent synchronous data link layer protocol developed by the International Organization for Standardization (ISO).

HDLC is based on IBM's SDLC protocol, which is the layer 2 protocol for IBM's Systems Network Architecture (SNA). It was extended and standardized by the ITU as LAP, while ANSI named their essentially identical version ADCCP.

Synchronous Data Link Control (SDLC) is a computer communications protocol. It is the layer 2 protocol for IBM's Systems Network Architecture (SNA). SDLC supports multipoint links as well as error correction. It also runs under the assumption that an SNA header is present after the SDLC header. SDLC was mainly used by IBM mainframe and midrange systems; however, implementations exist on many platforms from many vendors. The use of SDLC (and SNA) is becoming more and more rare, mostly replaced by IP-based protocols or being tunneled through IP (using AnyNet or other technologies)

What is LAP and HDLC?

HMOS=High Metal Oxide Semiconductor.

What is the full form of HMOS?

What is HMOS technology?

Can anyone please tell what is mos?

Please describe it in an easy language.

HMOS: Depletion-load nMOS/NMOS (n-channel metal-oxide-semiconductor) is a form of nMOS logic family which uses depletion-mode n-type MOSFETs as load transistors as a method to enable single voltage operation and achieve greater speed than possible with pure enhancement-load device.
