SkyHigh Memory S34SML0xG2 Spansion SLC NAND Flash Memory

SkyHigh Memory S34SML0xG2 Spansion SLC NAND Flash Memory is offered with 3.3VCC or VCCQ power supplies and with either an x8 or x16 I/O interface. The S34SML0xG2 has a cost-effective NAND cell for the solid-state mass storage market. The memory is divided into blocks so valid data can be preserved while old data is erased independently.

The page size for x8 is (2048 + spare) bytes; for x16 (1024 + spare) words. The implementation of an ECC is mandatory to extend the lifetime of NAND flash devices. The chip supports CE# do not care function, which allows a microcontroller to download code from the NAND flash memory. The CE# transitions do not stop the read operation.

The SkyHigh Memory S34SML0xG2 devices have a Read Cache feature for large files and can load data in a cache register while the previous data is transferred to the I/O buffers to be read.
