Latest Patents
Yuen holds a patent for "Master slice gate array integrated circuits with basic cells adaptable." This invention allows the input/output circuit cells of a master-slice gate array device to share the same diffusion and gate regions as the basic transistors. This design enables the input/output of the device to be defined at the metallization stage, rather than at the time the diffusion regions are formed. Consequently, a single size master-slice circuit device can be maintained in inventory. The array size is tailored to the customer's specifications, and the inputs/outputs are defined using CAD. The die can then be scribed into smaller units. His design incorporates long channel transistors in the feedback loop of memory cells, which eliminates the need for gating transistors, thereby reducing the number of transistors required for latches. To enhance drive capability, multiple transistors can be connected to form the input or output buffer without necessitating large transistors with extensive diffusion regions. Additionally, a metal silicide resistor and several discharge transistors, typically in the off condition, are linked to the node between an input/output pad and input/output buffer for electrostatic discharge protection.
