Memory
Memory is a semiconductor device that is used as data storage device on an integrated circuit. These devices are available in several formats CBRAM, DRAM, EEPROM, EERAM, EPROM, Flash, FRAM, NVSRAM, PCM (PRAM), PSRAM, RAM, and SRAM in either Non-Volatile or Volatile. These devices memory sizes range from 64 b to 6 Tb with the interface being I2C, MMC, Parallel, eMMC, Serial, Single Wire, SPI, UFS, Xccela Bus, and 1-Wire.
