内存,台湾译為记忆体,亦称为存储器,是一种利用半导体技术做成的电子装置,用来储存资料。电子电路的资料是以二进制的方式储存,内存的每一个储存单元称做记忆元记忆胞(Cell)。

分类

根据储存能力与电源的关系可以分为两类:

挥发性内存

挥发性(Volatile)内存:指的是当电源供应中断后,内存所储存的资料便会消失,一般称之为RAM。有两种主要的类型
  • DRAM:动态随机存取内存
  • SRAM:静态随机存取内存

非挥发性内存

主条目: ROM 非挥发性(Non-Volatile)内存:即使电源供应中断,内存所储存的资料并不会消失,重新供电后,就能够读取内存资料
  • ROM (Read-Only Memory,只读内存)
  • PROM (Programmable ROM,可编程只读内存)
  • EPROM (Erasable Programmable Read Only Memory,可抹除可编程只读内存)
  • OTPROM(One Time Programmable Read Only Memory,OTP,一次编程只读内存)
  • EEPROM (Electrically Erasable Programmable Read Only Memory,电子式可抹除可编程只读内存)
  • Flash memory (快闪存储器)
