Abstract: A compute-in-memory (CIM) circuit that enables a multiply-accumulate (MAC) operation based on a current-sensing readout technique. An operational amplifier coupled with a bitline of a column of bitcells included in a memory array of the CIM circuit to cause the bitcells to act like ideal current sources for use in determining an analog voltage value outputted from the operational amplifier for given states stored in the bitcells and for given input activations for the bitcells. The analog voltage value sensed by processing circuitry of the CIM circuit and converted to a digital value to compute a multiply-accumulate (MAC) value.

Abstract: Embodiments herein describe techniques for a thin-film transistor (TFT) above a substrate. The transistor includes a gate electrode above the substrate, and a channel layer above the substrate, separated from the gate electrode by a gate dielectric layer. The transistor further includes a contact electrode above the channel layer and in contact with a contact area of the channel layer. The contact area has a thickness determined based on a Schottky barrier height of a Schottky barrier formed at an interface between the contact electrode and the contact area, a doping concentration of the contact area, and a contact resistance at the interface between the contact electrode and the contact area. Other embodiments may be described and/or claimed.

Abstract: A binary CIM circuit enables all memory cells in a memory array to be effectively accessible simultaneously for computation using fixed pulse widths on the wordlines and equal capacitance on the bitlines. The fixed pulse widths and equal capacitance ensure that a minimum voltage drop in the bitline represents one least significant bit (LSB) so that the bitline voltage swing remains safely within the maximum allowable range. The binary CIM circuit maximizes the effective memory bandwidth of a memory array for a given maximum voltage range of bitline voltage.
