    摘要: Embodiments of the invention provide electronic synapse devices for reinforcement learning. An electronic synapse is configured for interconnecting a pre-synaptic electronic neuron and a post-synaptic electronic neuron. The electronic synapse comprises memory elements configured for storing a state of the electronic synapse and storing meta information for updating the state of the electronic synapse. The electronic synapse further comprises an update module configured for updating the state of the electronic synapse based on the meta information in response to an update signal for reinforcement learning. The update module is configured for updating the state of the electronic synapse based on the meta information, in response to a delayed update signal for reinforcement learning based on a learning rule.

    摘要: A sensing circuit and method for sensing match lines in content addressable memory. The sensing circuit includes an inverter electrically coupled in a feedback loop to a match line. The inverter includes an inverting threshold of the match line. The match line is charged to substantially a first voltage threshold during a pre-charge phase. An evaluation phase occurs when the match line voltage drops from substantially the first voltage threshold to substantially the second voltage threshold.

    摘要: A test structure for characterizing a production static random access memory (SRAM) array. The test structure includes a characterization circuit having multiple memory cell columns connected in series to form a ring configuration. The characterization circuit is fabricated on a wafer substrate in common with and proximate to a production SRAM array. The characterization circuit preferably includes SRAM cells having a circuit topology substantially identical to the circuit topology of memory cells within the production SRAM array. In one embodiment, the test structure is utilized for characterizing a multi-port memory array and includes multiple memory cell columns connected in series to form a ring oscillator characterization circuit. Each cell column in the characterization circuit includes multiple SRAM cells each having a latching node and multiple data path access nodes. Selection control circuitry selectively enables the multiple data path access nodes for the SRAM cells within the characterization circuit.
