Ground-referenced single-ended memory interconnect

A system is provided for transmitting signals. The system comprises a first processing unit, a memory subsystem, and a package. The first processing unit is configured to include a first ground-referenced single-ended signaling (GRS) interface circuit. The memory subsystem is configured to include a second GRS interface circuit. The package is configured to include one or more electrical traces that couple the first GRS interface to the second GRS interface, where the first GRS interface circuit and the second GRS interface circuit are each configured to transmit a pulse along one trace of the one or more electrical traces by discharging a capacitor between the one trace and a ground network.

Ground-referenced single-ended memory interconnect

A system is provided for transmitting signals. The system includes a ground-referenced single-ended signaling (GRS) driver circuit that is configured to pre-charge a first capacitor to store a first charge between a first output node and a first reference node based on a first input data signal during a first pre-charge phase and drive an output signal relative to a ground network based on the first charge during a first drive phase. A control circuit is configured to generate a first set of control signals based on the first input data signal and a first clock signal, where the first set of control signals causes the first GRS driver circuit to operate in either the first pre-charge phase or in the first drive phase.

Controlled buckling structures in semiconductor interconnects and nanomembranes for stretchable electronics

In an aspect, the present invention provides stretchable, and optionally printable, components such as semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed, and related methods of making or tuning such stretchable components. Stretchable semiconductors and electronic circuits preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention are adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.
