The authors report on the design, operation, and architectural implications of single and double floating-gate devices for nontraditional applications enabling low-power FPGAs and analog-to-digital converters, and propose a unified nonvolatile/volatile memory device.
New architectures for the switch box and connection block are proposed for use in an energy efficient field programmable gate array (FPGA) with bidirectional wiring. Power-hungry SRAMs are replaced by non-volatile nanocrystal floating gate (NCFG) devices that retain their state while the system power is off and do not need to be configured at boot up. The… (More)
Molecular electronics holds significant potential to outscale bulk electronic devices. However, practical issues have limited that potential to date. This paper reviews the function and design of molecular electronics and evaluates results to date in a circuits context.
The operation of a novel unified memory device using two floating-gates is described through experimental characterization of a fabricated proof-of-concept device and confirmed through simulation. The dynamic, nonvolatile, and concurrent modes of the device are described in detail. Simulations show that the device compares favorably to conventional memory… (More)
Integrating molecular memory devices into large scale arrays is a key requirement for translating the miniature size of molecular devices into ultradense memory systems. This in turn imposes constraints on the individual molecular memory devices. A circuit theory approach is used to derive a general parameterized memory circuit model, from which… (More)
