Abstract

A system-on-chip prototype implements a full integration of a 64-minute digital voice recorder/player embedding a 4 bit/cell multilevel digital flash memory. A speech coder/decoder (8 to 40 kbps), an MCU and an 8 Mcell/32 Mb multilevel flash memory with fully digital on-chip BIST solution are integrated in a 0.5 /spl mu/m embedded flash technology. The system features a modular architecture allowing full reuse and mix-and-match of its IP building blocks. The chip counts 13M transistors at 225 mm/sup 2/ area.
一个64分钟的单芯片录音/播放器,使用嵌入式4位/单元闪存
片上系统原型实现了64分钟数字录音机/播放器的完全集成,嵌入了一个4位/单元的多级数字闪存。语音编码器/解码器(8至40 kbps), MCU和8 Mcell/32 Mb多级闪存与全数字片上BIST解决方案集成在0.5 /spl mu/m嵌入式闪存技术中。该系统采用模块化架构,允许完全重用和混合匹配其IP构建模块。该芯片以225 mm/sup /面积计有13M个晶体管。
