	Write-only Memory (joke) Write-only memory (WOM), the opposite of read-only memory (ROM), began as a humorous reference to a memory device that could be written to but not read, as there seemed to be no practical use for a memory circuit from which data could not be retrieved. However, it was eventually recognized that write-only describes certain functionalities in microprocessor systems. The concept is still often used as a joke or euphemism for a failed memory device. The first use of the term is generally attributed to Signetics, whose ''write-only memory'' literature, created in 1972 as in-house practical joke, is frequently referenced within the electronics industry,. a staple of software engineering lexicons, and included in "best hoaxes" collections. Signetics A "Write-Only Memory" datasheet was created "as a lark" by Signetics engineer John G "Jack" Curtis,. inspired by a fictitious and humorous vacuum tube datasheet from the 1940s. Considered "an icebreaker", it was deliberately included in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Write-only Memory (engineering) 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. Hardware uses In 1972, WOM, an antithesis of read-only memory (ROM), was introduced as an inside practical joke perpetrated by Signetics. However, it was soon recognized that this concept actually describes certain functionalities in microprocessor systems. The most frequent occurren ...
