Abstract: A processor may include a memory controller and a cache memory. The memory controller, during a write operation to a main memory, generates a B-byte sized parity for A-byte sized data, stores the A-byte sized data and the B-byte sized parity through a single write command, and during a read operation from the main memory, reads the A-byte sized data and the B-byte sized parity through a single read command, performs error correction on the A-byte sized data based on the B-byte sized parity, and then transfers only the A-byte sized data to a cache memory. The cache memory receives the A-byte sized data from the memory controller or transmits the A-byte sized data to the memory controller, and includes at least one cache line that stores a plurality of an A-byte sized data.

Abstract: Provided are system on chips (SoC) and a computing devices including the SoC. The SoC may be configured to control an external main memory, and may include a memory controller configured to generate B-byte parity for A-byte data and detect an error in the A-byte data using the B-byte parity, wherein A and B are natural numbers, store the A-byte data and the B-byte parity to one memory block of the external main memory by transmitting a write command to the external main memory and the A-byte data and the B-byte parity to the external main memory and read the A-byte data and the B-byte parity from the one memory block of the external main memory by transmitting a read command to the external main memory, a data cache memory configured to transmit the A-byte data to and receive the A-byte data from the memory controller and cache the A-byte data, and a processor configured to access the external main memory.

Abstract: A vehicle includes a storage trench having a bottom surface and side surfaces. The bottom surface is recessed relative to a floor of the vehicle, a first side surface extends upwards from the bottom surface to the floor on a first side of the trench, and a second side surface extends upwards from the bottom surface to the floor on a second side of the trench. The trench extends between a first seat and a second seat of the vehicle, unobstructed from an occupant compartment to a storage compartment. The trench allows access from outside of the vehicle, for example, from either a forward or rearward storage compartment. An inset may be included along the bottom surface. The insert can be removed, by sliding for example, for cleaning or to help access stored gear. The trench is longer than either storage compartment, capable of storing relatively long gear or equipment.
