• In this project, theories of the cellular nonlinear network will be studied and the possibilities of using memristive devices in these networks will be investigated. A software model of prototype cellular nonlinear neural network accounting for the behaviors of memristive devices as the synaptic connections will be implemented and a series of simulations will be performed.
  • The Bitlet model is a new an analytical, parameterized,  modeling tool, developed in the ASIC2 lab. The Bitlet model can be used to estimate the performance and the power of a PIM-based system and thereby assess the affinity of workloads for PIM as opposed to traditional computing.In order to make Bitlet more beneficial, it has to be made more accessible to users by equipping it with new features and interactive graphical...
  • Ferroelectric Field Effect Transistor (FeFET) memory has shown the potential to meet the requirements of the growing need for fast, dense, low power and non-volatile memories.Integrating a layer of ferroelectric within the gate stack of a regular Field Effect Transistor (FET) enables the transistor to store data in the polarization state of the ferroelectric. In this project, we look for appropriate application of binary neural network (BNN) which can benefit...
  • In this project, the RF model of the indirectly heated four-terminal PCM RF switch will be improved and verified against experimental data. The model will be unified with an electro-thermal model of the device to perform optimizations of the device structure for different applications. This model will be used to explore the design constraints of these devices and to find the optimum device geometries for different applications.

  • In this project, a loaded-line phase shifter based on the PCM RF switch that we are developing in our group will be designed and evaluated. Phase shifters are fundamental devices to control the steer the beam in an antenna array and a great number of phase-shifters are required for this critical functionality in 5G and radar systems. PCM RF switches can increase the performance, while reducing the area overhead and...

  • A conventional address decoder is conceptually based on a multi-input AND gate that selects a memory row. A unique address of a memory row is set by hardwiring the direct and inverted address bits to the inputs of the AND gate. In a decoder position where the input address matches the hardwired pattern, the AND gate outputs ‘1’, selecting the memory row. The address of a memory row is permanently...

  • In this project, the students will perform characterization of a Resistive RAM (ReRAM) Crossbar array. They will work with a packaged device that contains a few arrays. The measurement setup will be based on a set of SMUs (Source Measure Units)  and a PC platform that control the measuring equipment. The students will use Python to create a set of tool that allow for automatic parameter extraction from memristive devices...

  • An STT-MRAM based multistate register has been designed, capable of storing multiple data bits within a single active register as a basic block of Continuous Flow Multi-Threading. This building block drastically reduces the number of cycles required to perform a context switch. Now we want to make it real i.e. integrate the register into a microprocessor and perform analysis to evaluate the gain in performance.

  • The growing demand to connect up the world is pushing wireless systems to be smaller than ever. This is part of the increasing move to a data driven world with billions of connected devices in the era of the Internet of Things (IoT) and space and energy are critical design criteria. Traditionally, miniaturization was possible owing to a focus in a single frequency and a single communication protocol. However, the...

  • Memristors are resistive devices with varying resistance which depends on the voltage applied to the device. The most natural memristor application is memory. However memristors can also be used for other applications, for example logic circuits. Once such approach is MRL (Memristor Ratioed Logic) - a hybrid CMOS-memristive logic family. In MRL, OR and AND logic gates are designed using memristors. The limitation of MRL is that every memristor-based logic...
