Latest Patents
Cullum's latest patents focus on innovative memory architecture. One of his key inventions is a DDR SDRAM where unidirectional row logic is associated with and connected to a single memory array. This design allows the unidirectional row logic to be located in the outward periphery of its associated array, avoiding placement within a throat region between two arrays. This strategic location enables the throat region to accommodate more bidirectional IO circuitry and signal lines servicing two arrays, ultimately increasing the performance of the SDRAM. Additionally, separate power bussing is employed for the memory arrays and IO circuitry, which prevents noise from the arrays from affecting the IO circuitry and signal lines of the throat region and vice versa.
