Abstract: An accelerator circuit is provided that includes an inverter chain having an input coupled to a data line and a sense circuit having inputs coupled to an output of the inverter chain and the data line. The sense circuit is configured to sense a rise toward a supply voltage on the data line or a fall toward a ground voltage on the data line. The accelerator circuit further includes an amplify circuit having inputs coupled to outputs of the sense circuit and an output coupled to the data line, where the amplify circuit is configured to amplify the data line toward the supply voltage or toward the ground voltage based on amplify enable signals output by the sense circuit.

Abstract: A memory tracking circuit activates a reset signal that resets a word-line pulse generator to switch the memory from an access state to a recess state. Activation is based on (i) a signal received at the far end of a tracking row after a propagation delay and (ii) a signal applied to a transistor-based gate delay. If the memory is in a fast PVT condition such that the gate delay is of less duration than, or substantially equal to, the propagation delay, then a slow-down circuit delays activation of the reset signal to allow sufficient access margin. The delay in the latter case is less than that in the former case. If the memory is in a slow PVT condition such that the gate delay is longer than the propagation delay, then the slow-down circuit does not delay activation of the reset signal to prevent excess access margin.

Abstract: A memory tracking circuit controls discharge duration of a tracking bit-line based on (i) a signal received at the far end of a tracking row after a propagation delay and (ii) a signal applied to a transistor-based gate delay. The tracking circuit (i) extends the discharge duration when one or more of (a) the propagation delay and (b) the transistor-based gate delay is shorter than an uncontrolled discharge duration of the tracking bit-line, and (ii) does not extend the discharge duration otherwise. Based on the discharge duration, the tracking circuit activates a reset signal that resets a clock-pulse generator to switch the memory from an access operation to a recess state. Controlling the discharge duration, and consequently the reset signal, based on the propagation delay and the gate delay allows the clock-pulse generator to adjust access times to account for the memory array configuration and process, temperature, and voltage conditions.
