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 μm 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 mm² area
