ALLIANCE MEMORY AS5F18G04SND-10LIN Flash Memory, NAND, 8 Gbit, 1G x 8bit, SPI, LGA, 8 Pins

AS5F18G04SND-10LIN is a serial peripheral interface (SPI) NAND flash memory. SPI NAND provides a low cost and low pin count solution to alternate SPI-NOR in high density non-volatile memory storage solution for embedded systems. SPI NAND is a flash memory device with SLC NAND of the standard parallel NAND. The serial electrical interface follows the industry-standard serial peripheral interface. The command sets are similar to SPI-NOR command sets. Some modifications have been made for handling NAND-specific functions. Besides, new features are added to extend applications. The SPI NAND has 8 pin counts in total, including six signal lines plus VCC and GND. The density is 1Gbit through 8Gbit. Each block of the serial NAND is subdivided into 64 programmable pages. Each page consists of a data storage region and a spare area. The data storage region is used to store user-programmed data and the spare area is typically used for memory management and error correction functions.
