Home › Product Center › SDRAM › DDR3/4 SDRAM › Winbond ›
This type of SDRAM is slower than the DDR variants, because only one word of data is transmitted per clock cycle (single data rate). But this type is also faster than its predecessors EDO-RAM and FPM-RAM which took typically 2 or 3 clocks to transfer one word of data.

Winbond stands out as one of the few companies worldwide with proprietary products and technology in both memory and logic integrated circuits. From product design, research and development, and wafer fabrication to the marketing of brand name products, Winbond endeavors to provide its global clientele with total integrated circuits solutions. Winbond's major product lines include Code Storage Flash Memory, TrustME® Secure Flash, Customized Memory Solution (CMS), and various Logic IC solutions.
