In high-density DRAM'S, a large peak current of typically 200-300mA occurs when sense amplifiers start latching in a conventional scheme (Figure la), resulting in intolerable power bus noise. Four-phase drive for PMOS restoring was reported to reduce the pe& current by triggering four pull-up transistors successively.[l] The initial sensing operation by NMOS latches, however, is more critical to signal margjn and sensing speed.

Ahtract-Register Alias Table (RAT) is a smart memory that is embedded in HPSm (High-Performance Substrate), a Berkeley data-flow CPU. It is a multiport memory that has content addressability and support for branch prediction and exception handling, in addition to conventional READ and WRITE operations. An experimental 1240-bit smart memory chip is implemented in a 1.6-pm double-metal scalable CMOS process. This memory performs 15 operations within a cycle time of 100 ns, has 34 658 transistors, occupies an area of 3.8 mm X 5.2 mm, and dissipates 0.51 W I117 [a.

为了实现具有大词汇量的连续语音识别系统，我们提出了ring-my-pmessor架构11-21，该架构具有两个特点:高度并行的DTW(Dynamie Time Warping)处理能力[31]。这是实现语音识别的主要算法。以及数组大小的灵活性。这使得可以根据词汇量来确定数组处理器所包含的PE(hxessing Element)的数量。本文介绍了用于实现高性能阵列处理器的PE-LSl体系结构和VLSI的实现方法。并对所得结果进行了讨论。
