发明名称 Memory management unit (MMU) to make only one time programmable (OTP) memory appear multiple times programmable (MTP)
摘要 Memory management units (MMUs) are disclosed. In one aspect, an MMU may have a first interface to a component. The first interface may receive one of a read of updated data from, and a write of updated data to, a virtual memory address. The virtual memory address may initially correspond to a first physical memory location in an only one time programmable (OTP) non-volatile memory (NVM). The MMU may have a remapping unit to remap a correspondence of the virtual memory address from the first physical memory location to a spare physical memory location. The MMU may also have a second interface to the OTP NVM. The second interface may allow the updated data to be read from or written to the spare physical memory location of the OTP NVM. Methods performed by the MMUs, and methods and articles useful for manufacturing MMUs, are also disclosed.
