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 I2C, 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. |
