Latest Patents
One of Liviu Calin's latest patents is titled "At-speed built-in self testing of multi-port compact sRAMs." This invention introduces a built-in self-test (BIST) for multi-port compact sRAM (CsRAM) that operates at the speed of the system. The testing circuitry allows for multiple random accesses of the CsRAM per system clock cycle, enabling the detection of timing-related defects. The CsRAM is virtually partitioned into "k" sections, which are tested simultaneously from different ports using identical and complementary test data. This innovation utilizes a conventional BIST controller with minimal additional hardware.
Another significant patent is focused on "Content addressable memory cells and words." This invention addresses the need for modifications to CAM cell designs as supply voltages decrease. In this design, when a reference bit matches a stored bit, p-channel pass transistors within the CAM cell can pass a full logical high to an n-channel chain transistor. This results in increased transition speed, decreased degradation, and reduced power dissipation. The use of p-channel pass transistors enhances performance compared to n-channel pass transistors, showcasing Liviu's innovative approach to memory technology.
