PLC系统中的存储器主要用于存放系统程序、用户程序和工作状态数据。PLC的存储器包括系统存储器和用户存储器。
（1）系统存储器
系统存储器用来存放由PLC生产厂家编写的系统程序，并固化在ROM内，用户不能更改。它使PLC具有基本的功能，能够完成PLC设计者规定的各项工作。系统程序质量的好坏很大程度上决定了PLC的性能。
（2）用户存储器
用户存储器包括用户程序存储器（程序区）和数据存储器（数据区）两部分。用户程序存储器用来存放用户针对具体控制任务采用PLC编程语言编写的各种用户程序。用户程序存储器根据所选用的存储器单元类型的不同（可以是RAM、EPROM或EEPROM存储器），其内容可以由用户修改或增删。用户数据存储器可以用来存放（记忆）用户程序中所使用器件的ON/OFF状态和数据等。用户存储器的大小关系到用户程序容量的大小，是反映PLC性能的重要指标。
