The 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 2048 + spare bytes for x16 1024 + spare words. 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 device load the data in a cache register while the previous data is transferred to the I/O buffers to be read. In multiplane operations, data in the page can be read out at 25ns cycle time per byte. The I/O pins serve as the ports for command and address input as well as data input/output.
