A semiconductor integrated circuit device includes a data bit storage memory which stores data bits, a code bit storage memory which stores code bits, and an ECC circuit. The memory access unit comprises an output port for providing access requests for lists of addresses in a memory over a link to a memory controller. A socket may include a socket body that is generally tubular in shape, a socket face provided at a first end of the socket body, a receiving wall extending from an outer periphery of the socket face and extending in a direction away from the socket body, a plurality of socket terminals provided on the socket, and a resilient clip provided on an inner side of the receiving wall. 01-10 pbw of a radical initiator or initiator mixture, and graft-polymerizing at reaction temperatures of 30-120\xb0 C.
