What is Semiconductor Memory?

What is Semiconductor Memory?　 Semiconductor memory is a type of semiconductor device tasked with storing data.
DRAM ＜Semiconductor Device Principles＞ DRAM memory cells consist of one transistor and one capacitor.
SRAM ＜Semiconductor Device Principles＞ The memory cell structure of SRAM is comprised of 6 transistors per cell for low power models and 4 transistors in high density versions.
Mask ROM ＜Semiconductor Device Principles＞ The memory cell structure of Mask ROM utilizes a NAND configuration consisting of one transistor per cell to achieve high integration density.
EEPROM ＜Semiconductor Device Principles＞ EEPROM memory cells feature a two-transistor structure composed of one memory and one select transistor.
Flash Memory ＜Semiconductor Device Principles＞ The area per bit for flash memory with a minimum rule of F is 4F² for NAND types and 10F² for NOR.
Interface Selection Generally, serial EEPROMs utilize 3 types of interfaces - Microwire, SPI, and I²C.
Pin Layout and Functions Explains the pin layout and functions of the three common interfaces for serial EEPROMs (I²C, SPI, Microwire).
Command Comparison EEPROM Command Comparison: Provides a comparative illustration of the commands possessed by each of the three common interfaces for serial EEPROMs (I²C, SPI, Microwire).
Application Example: Configuring Multiple EEPROMs (I²C) Configuration example using multiple I²C interfaces. I²C can be used for multiple devices by configuring the address setting of each device separately.
Application Example: Configuring Multiple EEPROMs (SPI) Configuration example using multiple SPI interfaces. With SPI, the CSB pin of each device is independently controlled by the bus master.
Application Example: Configuring Multiple EEPROMs (Microwire) Configuration example using multiple Microwire interfaces. Microwire independently controls the CS pin of each device via the bus master.
