SPI(x1/x2/x4) NAND Flash

GENERAL DESCRIPTION

SPI (Serial Peripheral Interface) NAND Flash provides an ultra cost-effective while high density non-volatile memory

storage solution for embedded systems, based on an industry-standard NAND Flash memory core. It is an attractive

alternative to SPI-NOR and standard parallel NAND Flash, with advanced features:

• Total pin count is 8, including VCC and GND

• Density is 2Gbit

• Superior write performance and cost per bit over SPI-NOR

• Significant low cost than parallel NAND

This low-pin-count NAND Flash memory follows the industry-standard serial peripheral interface, and always remains the

same pin out from one density to another. The command sets resemble common SPI-NOR command sets, modified to

handle NAND specific functions and added new features. GigaDevice SPI NAND is an easy-to-integrate NAND Flash

memory, with specified designed features to ease host management:

• User-selectable internal ECC. ECC code is generated internally during a page program operation. When a page

is read to the cache register, the ECC code is detect and correct the errors when necessary. The 64-bytes spare area

is available even when internal ECC enabled. The device outputs corrected data and returns an ECC error status.

• Internal data move or copy back with internal ECC. The device can be easily refreshed and manage garbage

collection task, without need of shift in and out of data.

•Power on Read with internal ECC.It is programmed and read in page-based operations, and erased in block-based

operations. Data is transferred to or from the NAND Flash memory array, page by page, to a data register and a cache

register. The cache register is closest to I/O control circuits and acts as a data buffer for the I/O data; the data register

is closest to the memory array and acts as a data buffer for the NAND Flash memory array operation. The cache

These devices also use a SPI status register that reports the status of device operation.
