An application specific embeddable flash memory system for non-volatile storage of code, data and bit-streams for embedded FPGA configurations

Abstract

A 8 Mb application-specific embeddable flash memory is presented. It features 3 content-specific I/O ports, delivers a peak read throughput of 1.2 GB/S, and, combined with a special automatic programming gate voltage ramp generator circuit, a programming rate of 1Mbyte/s for non-volatile storage of code, data and embedded FPGA bit stream configurations. The test chip has been designed using a NOR type 0.18 /spl mu/m flash embedded technology with 1.8 V power supply, 2 poly, 6 metal and memory cell size of 0.35 /spl mu/m/sup 2/.
