A High-Resolution Non-Volatile Analog Memory Cell
نویسندگان
چکیده
A 3-transistor nonvolatile analog storage cell with 14 bits effective resolution and railto-rail buffered voltage output is presented. The memory, which consists of charge stored on a MOS transistor floating gate, is written by means of hotelectron injection and erased by means of gate oxide tunneling. The circuit allows simultaneous memory reading and writing; by writing the memory under feedback control, errors due to oxide mismatch or trapping can be nearly eliminated. Small size and low power consumption make the cell especially attractive for use in analog neural networks. The cell is fabricated in a 2 μm n-well silicon BiCMOS process available from MOSIS.

متن کاملOptimization of Non-volatile Memory Cell and Energy Consumption in Robot Systems by Synthesized Silicon Nanoparticles via Electrical Discharge
In this paper, we propose to optimize manufacturing methods of memory cells by produced silicon nanoparticles via electrical spark discharge of silicon electrodes in water to reduce the energy consumption for low power applications. The pulsed spark discharge with the peak current of 60 A and a duration of a single discharge pulse of 60 µs was used in our experiment. The structure, morphology, ...
متن کاملMemristor Bridge Synapse Application for Integrate and Fire and Hodgkin-Huxley Neuron Cell
Memory resistor or memristor is already fabricated successfully using current nano dimension technology. Based on its unique hysteresis, the amount of resistance remains constant over time, controlled by the time, the amplitude, and the polarity of the applied voltage. The unique hysteretic current-voltage characteristic in the memristor causes this element to act as a non-volatile resistive me...

The system memories requirement depends greatly on the nature of the applications which run on the system. Memory performance and capacity requirements are small for simple, low cost systems. In contrast, memory throughput can be the most critical requirement in complex, high performance systems. The following general types of memories can be used in systems such as Volatile and non-volatile me...
