The S34ML04G100BHI000 is a 4GB SLC NAND Flash Memory for embedded. It is offered in 3.3VCC and VCCQ power supply and with x8 or x16 I/O interface. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. The page size for x8 is bytes for x16 (1024 + 32) words. Each block can be programmed and erased up to 100000 cycles with ECC (error correction code) on. To extend the lifetime of NAND flash devices, the implementation of an ECC is mandatory. The chip supports CE# don"t care function. This function allows the direct download of the code from the NAND flash memory device by a microcontroller, since the CE# transitions do not stop the read operation. The device has a read cache feature that improves the read throughput for large files. During cache reading, the devices load the data in a cache register while the previous data is transferred to the I/O buffers to be read.
