Complementary metal–oxide–semiconductor, abbreviated as CMOS /ˈsiːmɒs/, is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analog circuits such as image sensors (CMOS sensor), data converters, and highly integrated transceivers for many types of communication. In 1963, Frank Wanlass patented CMOS while working for Fairchild Semiconductor. It is also sometimes referred to as complementary-symmetry metal–oxide–semiconductor.The words “complementary-symmetry” refer to the typical design style with CMOS using complementary and symmetrical pairs of p-type and n-type metal oxide semiconductor field effect transistors (MOSFETs) for logic functions.

Sandisk was founded in 1988 by Eli Harari, Sanjay Mehrotra and Jack Yuan, incorporated at the time as SunDisk. SanDisk Corporation is an American manufacturer of flash memory products, including memory cards and readers, USB flash drives, and solid state drives. As of February 2015, SanDisk is the third-largest manufacturer of flash memory. On May 12, 2016, SanDisk was acquired by hard drive manufacturer Western Digital in a US$19 billion deal.SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage. On May 10, 2000 the Toshiba Corporation of Japan and the SanDisk Corporation said that they would jointly form a new semiconductor company to produce advanced flash memory, primarily for digital cameras.

What is Logic Card ?
A motherboard is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. It is well known as Logic Card & Main Board too. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset’s input/output and memory controllers, interface connectors, and other components integrated for general purpose use and applications.
