The AU-M3001 Flash Controller Core is a versatile NAND/NOR flash controller that supports
various types of NAND and NOR flash chips from several manufacturers. The Flash Controller
data bus width is user configurable to 8, 16, 32 or 64 bits. The Flash Controller supports NAND
flash memory systems from 8 Mbytes to 512 Gbytes, and NOR flash memory systems from 512
Kbytes to 1 Gbyte. Flash chip timing parameters are both user configurable at reset with Verilog
parameters and software programmable to support a wide range of flash speed grades and system
clock frequencies. The Flash Controller is available as a synthesizable Verilog model from
Aurora VLSI, Inc.
