| Popis: | In this work, we present a compact modeling of capacitorless A2RAM memory cell. It is obtained by combining A2RAM DC compact model with an equivalent circuit that mimics the memory state. The DC modeling is achieved by considering the A2RAM architecture as the combination of a SOI transistor in parallel with a variable-resistance bridge. The crucial aspect is the analytical description of the bridge threshold voltage. The complete A2RAM compact model is implemented in Verilog-A to allow the use of SPICE simulator. DC and memory characteristics are validated by TCAD. SPICE simulations show the operation of 2 × 2 A2RAM matrix. |
