GENERAL DESCRIPTION
OneNAND is a single-die chip with standard NOR Flash interface using NAND Flash Array. This device is comprised of logic and NAND Flash Array and 5KB internal BufferRAM. 1KB BootRAM is used for reserving bootcode, and 4KB DataRAM is used for buffering data. The operating clock frequency is up to 54MHz. This device is X16 interface with Host, and has the speed of ~76ns random access time. Actually, it is accessible with minimum 4clock latency(host-driven clock for synchronous read), but this device adopts the appropriate wait cycles by programmable read latency. OneNAND provides the multiple sector read operation by assigning the number of sectors to be read in the sector counter register. The device includes one block sized OTP(One Time Programmable), which can be used to increase system security or to provide identification capabilities.
