Nikkeibp.Co.JP reported that 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.
The serial transfer technology will also be made available for use in SD Input/Output (SDIO), with the objective of making it possible to use the SD bus as the internal bus for embedded systems. According to a source involved with the SD Association of the US, "Specifically, the target is the mobile phone internal bus."
