1.2 General Overview

Flex-MuxOneNAND™ is a monolithic integrated circuit with a NAND Flash array using a NOR Flash interface.

The chip integrates system features including:

• A BootRAM(1KB) and bootloader

• 4KB DataRAM buffers

• A High-Speed x16 Host Interface

• On-chip Error Correction

• On-chip NOR interface controller

This on-chip integration enables system designers to reduce external system logic and use high-density NAND Flash in applications that

would otherwise have to use more NOR components.

Flex-MuxOneNAND takes advantage of the higher performance NAND program time, low power, and high density and combines it with the

synchronous read performance of NOR. The NOR Flash host interface makes Flex-MuxOneNAND an ideal solution for mobile applications

that have large, advanced multimedia applications and operating systems and need high performance.

When integrated into a Samsung Multi-Chip-Package with Samsung Mobile DDR SDRAM, designers can complete a high-performance, small

footprint solution.

The device operates up to a maximum host-driven clock frequency of 66MHz / 83MHz for synchronous reads at Vcc(or Vccq. Refer to chapter

4.2) with 4~7-clock latency. Appropriate wait cycles are determined by programmable read latency.

Flex-MuxOneNAND provides for multiple sector read operations by assigning the number of sectors to be read in the sector counter register.

The device includes one block-sized OTP (One Time Programmable) area and user-controlled 1st block OTP(Block 0) that can be used to

increase system security or to provide identification capabilities.
