Article Overview

Memory is a semiconductor device used for data storage. It is divided into two types: non-volatile and volatile, with different formats, capacities, speeds, power consumption, etc. This article will introduce the different characteristics of memory to help readers make better choices.

Memory is a semiconductor device used as a data storage device on an integrated circuit. These devices are classified as either non-volatile or volatile and come in formats such as CBRAM, DRAM, EEPROM, EERAM, EPROM, Flash, FRAM, NVSRAM, PCM (PRAM), PSRAM, RAM, and SRAM. These devices are available in capacities ranging from 64b to 6Tb and interfaces such as I2C, MMC, parallel, eMMC, serial, 1-wire, SPI, UFS, Xccela bus, and 1-wire.

When selecting memory, you need to pay attention to the memory characteristics and make your selection based on several important indicators such as volatility, storage capacity, access speed, power consumption, reliability, price, and integration.

Vendor Device Package: This is the vendor's name for the package that the device comes in. This is vendor specific. Generally speaking, when designing a circuit, it is best to use the actual dimensions from the data sheet rather than making choices based on this term.
