AH-7921 is a structurally unique synthetic opioid analgesic that has recently entered the drug arena in Europe, the USA, and Japan. Although it was synthesized and patented in the mid-1970s, it was first identified in a seized sample purchased via the Internet in July 2012 and formally brought to the attention of the European Union early warning system in(More)
This paper proposes implicit-storing to extend the logical capacity of a memory array without increasing its physical capacity by leveraging the array's error-correction-codes to infer the implicitly stored bits. Implicit-storing is related to error-code-tagging, a technique that distinguishes between faults in data and invariant attributes of a location(More)
Total Cost of Ownership (TCO) is a key optimization metric for the design of a datacenter. This paper proposes, for the first time, a framework for modeling the implications of DRAM failures and DRAM error protection techniques on the TCO of a datacenter. The framework captures the Effects and interactions of several key parameters including: the choice of(More)
This work introduces Check-on-Write: a memory array error protection approach that enables a trade-off between a memory array's fault-coverage and energy. The presented approach checks for error in a value stored in an array before it is overwritten rather than, as currently done, when it is read (check-on-read). This aims at reducing the number and energy(More)
