With the coming of ‘Big Data‘ era, high-energy-efficiency database is demanded for the Internet of things (IoT) application scenarios. The emerging Resistive Random Access Memory (RRAM) has been considered as an energy-efficient replacement of DRAM for next-generation main memory. In this paper, we propose an RRAM-based SQL query unit with process-in-memory characteristic. A storage structure for...
In many application domains, data are represented using large graphs involving millions of vertices and billions of edges. Graph exploration algorithms, such as breadth-first search (BFS), are largely dominated by memory latency and are challenging to process efficiently. In this paper, we present a reconfigurable hardware methodology for efficient parallel processing of large-scale graph exploration...
We observed Single Bit Read Disturb failure in SRAM blocks with embedded Flash process. Such failures are not observed in pure logic process because pure logic process does not require additional thermal budget. In embedded Flash process, static Noise Margin (SNM) and leakage current degrades, causing more Single Bit Failure (SBF) at high VCC and/or high temperature. We optimized SRAM bitcell's transistor...
