Latest Patents

Kumagaya's latest patents include an information processing system and a memory system. The memory system features a memory device that includes memory chips and a controller. The controller is designed with first processors that perform initial processing of network packets at the network and transport layers of a network protocol. Additionally, it has second processors that handle processing related to the memory chips. The controller extracts tag information from network packet headers, selects the appropriate first processor linked to a specific memory chip, and directs it to process the network packet. This process enables the associated second processor to perform further processing based on the packet's payload.

Another significant patent is a memory system that incorporates a packet protection circuit. This circuit consists of multiple CRC calculation circuits, each responsible for calculating a CRC of M-byte data. The system also includes a selector that outputs the CRC calculation result from one of the circuits, along with a second CRC calculation circuit that computes a CRC of L-byte data. This design is crucial for detecting errors in data packets transmitted between the host interface unit and the host device.
