Winbond Electronics Corporation was founded in 1987 in Hsinchu Science Park, Taiwan. Until now the Company was one of the bigest manufacturer of LSI integrated circuits (microcontrolles, memories, telecommunications ICs, computer logic ICs and sound ICs) in the world. In July 2008 was created the new company, Nuvoton Technology Corporation , as a wholly-owned subsidiary of Winbond which took over the whole Winbond's products lines of Computer Logic and Consumer Logic ICs.
Today Winbond focuses only on the Memory Products design and manufacturing with four main products groups: Mobile RAM, DRAM, Graphics DRAM and Flash Memory ICs.

Winbond is IECQ, ISO 9001, ISO 14001 and QS 9000 certified. Many of its products meet the AEC-Q100 specification and are qualified for Automotive grade.
Winbond has set up subsidiaries in the USA, Japan, and Hong Kong.

The Marthel Company has in its offer full range of Winbond's memory products.
