可编程只读存储器（英语：Programmable read-only memory），缩写为PROM或FPROM，是一种电脑存储记忆芯片，每个比特都由熔丝或反熔丝的状态决定数据内容。这种内存用作永久存放程序之用。常用于电子游戏机、电子词典等预存固定数据或程序的各式电子产品之上。PROM与狭义的ROM（Mask ROM）的差别在于前者可在IC制造完成后才依需要写入数据，后者的数据需在制造IC时一并制作在里面。

A programmable read-only memory (PROM) or field programmable read-only memory (FPROM) or one-time programmable non-volatile memory (OTP NVM) is a form of digital memory where the setting of each bit is locked by a fuse or antifuse. It is one of the type of ROM (read-only memory). The data in them is permanent and cannot be changed. PROMs are used in digital electronic devices to store permanent data, usually low level programs such as firmware (microcode). The key difference from a standard ROM is that the data is written into a ROM during manufacture, while with a PROM the data is programmed into them after manufacture. Thus, ROMs tend to be used only for large production runs with well-verified data, while PROMs are used to allow companies to test on a subset of the devices in an order before burning data into all of them.
