Latest Patents

Heymann's latest patents include a "Method and apparatus for improved memory module supply current surge response." This invention describes an apparatus that incorporates a power management integrated circuit (PMIC) designed to generate a supply voltage for a memory module. The PMIC performs measurements during the initialization of the memory module to assess the worst-case current draw and the corresponding droop in the supply voltage. In response to detecting a surge in the memory module's current draw during operation, the PMIC applies a step-up to the supply voltage based on these measurements.

Another notable patent is the "Method and apparatus to reduce power consumption for refresh of memory devices on a memory module." This innovation reduces power consumption by assigning each memory device on the module to one of several sub-channels, each equipped with a thermal sensor. The refresh rate is increased only for memory devices operating above a predefined high temperature, leading to reduced power requirements and increased maximum bandwidth for the memory module.
