SD Memory Cards Hit 300MBps with Serial Transfer, New Pin



The next-generation Secure Digital (SD) memory card standard, SD Specification Version 4.00 (provisional name), is slated for completion in spring 2010, and may well feature a new dedicated pin for high-speed data transfer (Table 1). The plan is to use low-voltage differential signaling (LVDS) to boost the max data transfer rate on the read read/write bus (the “SD bus”) from its current 104Mbyte/s to 300Mbyte/s.
