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性能的重要指标之一。
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中程序的破坏，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。现在有许多PLC直接采用EEPROM作为用户存储器。
