— The paper presents experimental demonstration of 6-bit digital-to-analog (DAC) and 4-bit analog-to-digital conversion (ADC) operations implemented with a hybrid circuit consisting of Pt/TiO 2-x /Pt resistive switching devices (also known as ReRAMs or memristors) and a Si operational amplifier (op-amp). In particular, a binary-weighted implementation is… (More)

— We have modified a commercial NOR flash memory array to enable high-precision tuning of individual floating-gate cells for analog computing applications. The modified array area per cell in a 180 nm process is about 1.5 μm 2. While this area is approximately twice the original cell size, it is still at least an order of magnitude smaller than in… (More)

The purpose of this work was to demonstrate the feasibility of building recurrent artificial neural networks with hybrid complementary metal oxide semiconductor (CMOS)/memristor circuits. To do so, we modeled a Hopfield network implementing an analog-to-digital converter (ADC) with up to 8 bits of precision. Major shortcomings affecting the ADC's precision,… (More)
