DIFFERENT TYPES OF MEMORY INTEGRATED IN ONE CHIP BY USING A NOVEL PROTOCOL

摘要

A semiconductor chip contains four different memory types, EEPROM, NAND Flash, NOR Flash and SRAM, and a plurality of major serial/parallel interfaces such as l2C, SPI, SDI and SQI in one memory chip. The memory chip features write- while-write and read-while-write operations as well as read-while-transfer and write- while-transfer operations. The memory chip provides for eight pins of which two are for power and up to four pins have no connection for specific interfaces and uses a novel unified nonvolatile memory design that allow the integration together of the aforementioned memory types integrated together into the same semiconductor memory chip.
