In information technology, a write-only memory (WOM) is a memory location or register that can be written to but not read. In addition to its literal meaning, the term may be applied to a situation when the data written by one circuit can be read only by other circuitry. The most common occurrence of the latter situation is when a processor writes data to a write-only register of hardware the processor is controlling. The hardware can read the instruction but the processor cannot. This can lead to problems in producing device drivers for the hardware. Write-only memories also find applications in security and cryptography as a means of preventing data being intercepted as it is being decrypted. (en) WOM är en engelsk akronym som uttyds write only memory. WOM är vanligt på äldre[när?] grafikkort där det endast går att skriva till bilden med processorn men inte att läsa den. Vanligtvis har dessa minnen en buss om 8 eller 16 bitar mot huvudprocessorn samt en enbitars ROM-port i den andra ändan där grafikkortets processor läser de pixlar som skall visas en efter en i samma ordning som de visas på datorns skärm.
