Abstract: A static random-access memory is provided with a double-pumped operation in which a read operation to a multiplexed group of columns of bitcells may occur in a first portion of a memory clock cycle and in which a write operation to a write-selected column in the multiplexed group of columns of bitcells may occur in a second portion of the memory clock cycle. The write operation to the write-selected column occurs without any precharging of bit lines in the write-selected column during read and write operations.

Abstract: Vertical channel field-effect transistors (VCFETs) with reduced contact resistance and/or parasitic capacitance, and related fabrication methods. In exemplary aspects, to reduce contact resistance of the VCFET, an end portion of the vertical channel has a semiconductor structure that has an expanded width in the horizontal direction parallel to the substrate surface. This provides a greater area to form a contact for a source/drain to reduce contact resistance of the VCFET. To reduce the parasitic capacitance between the gate and a contact of the VCFET, the spacer includes one or more air gaps that form an air spacer(s) between the gate and the contact to reduce the overall average permittivity of the spacer. In one example, the air spacer(s) of the VCFET is elongated in the horizontal direction parallel to the substrate surface (and perpendicular to the vertical direction of the vertical channel) to further reduce the parasitic capacitance.

Abstract: A bit line charge sharing precharge circuit is provided that precharges a bit line pair during a charge sharing period in which the bit line pair is isolated from a memory power supply voltage. Prior to the charge sharing period, one of the bit lines in the bit line pair was charged to the memory power supply voltage whereas a remaining one was either fully or partially discharged. Charge thus flows from the charged bit line to the discharge bit line during the charge sharing period to precharge the bit lines for a current read or write operation.
