In this paper, a write-back mechanism, which may employ security, is employed to enforce usage restrictions, such as an expiration date, usage count limit or data access fee for the acquired data.Abstract:
A destructive-read memory is one that the process of reading the memory causes the contents of the memory to be destroyed. Such a memory may be used in devices that are intended to acquire data that may have associated usage restrictions, such as an expiration date, usage count limit, or data access fee for the acquired data. Typically, to enforce usage restrictions, and protect against theft, complex and often costly security techniques are applied to acquired data. With destructive-read memory, complex and costly security is not required for stored data. In one embodiment, a write-back mechanism, which may employ security, is responsible for enforcing usage restrictions. If the write-back mechanism determines continued access to acquired data is allowed, then it writes back the data as it is destructively read from the memory.read more

Cycle-skipping DRAM for power saving
TL;DR: In this paper, a DRAM memory is used to save power by skipping unnecessary read, write, and refresh cycles of the internal memory core, e.g. due to the destructive read nature of the DRAM.
