OneNAND128 FLASH MEMORY
2. 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 3KB internal BufferRAM. 1KB BootRAM is used for reserving bootcode, and 2KB 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.

- Inputs for addresses during operation, which are for addressing BufferRAM & Register.
Data Inputs/Outputs
- Inputs data during program and commands during all operations, outputs data during memory array/ register read cycles. Data pins float to high-impedance when the chip is deselected or outputs are disabled.
Interrupt
Notifying Host when a command has completed. It is open drain output with internal resistor(~50kohms). After power-up, it is at hi-z condition. Once IOBE is set to 1, it does not float to hi-z condition even when the chip is deselected or when outputs are disabled.
Ready
Indicates data valid in synchronous read modes and is activated while CE
Clock

BSC (BufferRAM Sector Count): this field specifies the number of sectors to be read or programmed or copy back programmed. Its maximum count is 2 sectors at 0(default value)value. For a single sector access, it should be programmed as value 1 and it should be programmed as value 0 for two sectors. However internal RAM buffer reached to 1 value(max. value), it counts up to 0 value to satisfy BSC value. for example) if BSA=1101, BSC=0, then selected BufferRAM are ’1101->1100’.
BSA (BufferRAM Sector Address): It is the place where data is placed and specifies the sector 0~1 in the internal BootRAM and DataRAM. BSA[3] is the selection bit between BootRAM and DataRAM. BSA[2] is the selection bit between DataRAM0 and DataRAM1. BSA[0] is the selection bit between Sector0 and Sector1 in the internal BootRAM and DataRAM. While one of BootRAM or DataRAM0 interfaces with memory, the other RAM is inaccessible.

This R/W register describes the operation of the OneNAND interface. Note that all commands should be issued right after INT is turned from ready state to busy state. (i.e. right after 0 is written to INT register.) After any
command is issued and the corresponding operation is completed, INT goes back to ready state. (00F0h and 00F3h may be accepted during busy state of some operations. Refer to the rightmost column of the command register table above.)
