This paper presents a built-in self-test (BIST) scheme, which consists of a flexible pattern generator and a practical on-macro two-dimensional redundancy analyzer, for GHz embedded SRAMs. In order to meet the system requirements and to detect a wide variety of faults or performance degradation resulting from recent technology advances, the microcode-based(More)
FD,(X, Y) = i < n implies that the faulty bit slices must be in the On Error Indication for Totally Self-Checking Systems range from max (0, i k + 1) to (i + 2k 1) bit slices. Theorem 5: If the failures in a bit-sliced ripple-carry adder or a TAKASHI NANYA AND TOSHIAKI KAWAMURA bit-sliced carry-look-ahead adder are confined to (k 1) adjacent bit slices and(More)
Plumbacyclopentadienylidenes, in which the lead atoms have divalent states and are coordinated by THF, pyridine and N-heterocyclic carbene, were synthesized and characterized. The THF- and pyridine-stabilized compounds can be regarded as rare examples of hypervalent 10-X-4 species. The equilibrium between the THF adduct and the free(More)
We carried out a series of zeroth-order regular approximation (ZORA)-density functional theory (DFT) and ZORA-time-dependent (TD)-DFT calculations for molecular geometries, NMR chemical shifts, nucleus-independent chemical shifts (NICS), and electronic transition energies of plumbacyclopentadienylidenes stabilized by several Lewis bases, (Ph)2 ((t) BuMe2(More)
