This week, Spansion Inc. released the Spansion FL-S NOR Flash memory family at 65nm, which it reports is the industry’s fastest serial Flash memory. On Monday, I spoke with Ajay Bhatia, director of product marketing, at Spansion about this new memory. He tells me that Spansion aims to change the way people think about serial peripheral interface (SPI) memory, positioning it for higher performance applications. The FL-S NOR Flash product demonstrates read performance of up to 66 MB/s, which will allow for faster execute in place (XiP) operation. This is a departure from the typical offerings in SPI memory. Bhatia notes that this is significantly more performance than Spansion's previous generation NOR Flash and it surpasses competing solutions (typically 54 MB/s) by more than 20%. The fast read speeds can enable rapid boot times are particularly important for automotive displays and electronic programming guides.
In addition, the new Flash features up to 1.5 MB/s write speed (three times faster than current SPI solutions in the market). Spansion further claims five times faster chip erase (0.13 seconds versus 0.7 seconds) coupled with the three times faster programming speed (23 seconds versus 66 seconds). With this product, Spansion is looking to move its SPI Flash into automotive, home networking, smart meters, and WiMAX applications.
Another notable feature of the new FL-S NOR Flash memory is its security features. The memory provides enhanced security with temporary or permanent block write protection, permanent sector lock, advanced sector protection (including password protection mode) and a 1kB one-time programmable (OTP) region with a 128-bit ID. This is particularly relevant for smart meter applications.
