Latest Patents

Among his latest innovations, one notable patent is a method for hybrid compression for large history compressors. This patent describes a compression engine and method designed to optimize high compression of content addressable memory (CAM) and enhance the efficiency of static random access memory (SRAM). This invention synchronizes a CAM with a small near history buffer and an SRAM with a larger far history buffer, enabling parallel processing of input streams through both components. This design allows an encoder to select the longest matching strings for the compressed output from both the near and far history components, with further optimizations facilitated by selectively disabling one of the compressors.

Another significant patent involves out-of-place presetting based on an indirection table. This innovation provides a PreSET region in a memory device, which contains lines of memory that have been PreSET. The method allows for write operations on out-of-place lines by writing to the PreSET region, while the indirection table maintains a mapping of logical pages to corresponding physical pages.
