Title: Frank P. Cartman: Innovator in Memory Access Systems
Introduction
Frank P. Cartman is a notable inventor based in Poughquag, NY (US). He has made significant contributions to the field of memory access systems, holding a total of 2 patents. His work focuses on improving the efficiency and reliability of memory systems, particularly in dynamic random access modules (DRAMs).
Latest Patents
Cartman's latest patents include a memory access system that features a memory controller with memory redrive. This innovative system enhances memory access by allowing both the memory controller and the main memory hardware to remember the row address of the last access. By redriving the row address to the DRAMs after each access, the memory controller can streamline command sequences, reducing the need to provide a row address for every command.
Another significant patent is the multi-bit error scattering arrangement designed to provide fault tolerance. This invention prevents the alignment of multiple defective bit storage locations within a memory array. The memory comprises a matrix of separate memory chips, each containing a large number of individually addressable bit locations. During memory read operations, data words are transferred from the memory array to a buffer, with steering logic that allows for selective rearrangement of chips based on defect data stored in an error map.
