存储器主要有两种：一种是可读/写操作的随机存储器RAM，另一种是只读存储器ROM、PROM、EPROM 和EEPROM。在PLC中，存储器主要用于存放系统程序、用户程序及工作数据。
系统程序是由PLC 的制造厂家编写的，和PLC的硬件组成有关，完成系统诊断、命令解释、功能子程序调用管理、逻辑运算、通信及各种参数设定等功能，提供PLC运行的平台。系统程序关系到PLC的性能，而且在PLC使用过程中不会变动，所以是由制造厂家直接固化在只读存储器ROM、PROM或EPROM中，用户不能访问和修改。
用户程序是随PLC的控制对象而定的，由用户根据对象生产工艺的控制要求而编制的应用程序。为了便于读出、检查和修改，用户程序一般存于CMOS静态RAM中，用锂电池作为后备电源，以保证掉电时不会丢失信息。为了防止干扰对RAM中程序的***，当用户程序经过运行正常，不需要改变，可将其固化在只读存储器EPROM中。现在有许***LC直接采用EEPROM作为用户存储器。
