摘要:
A covering material composition for a golf ball, which comprises an ionomer resin and a diene rubber, the diene rubber being dispersed in the ionomer resin. The covering material composition is produced by mixing the ionomer resin with the diene rubber to disperse the diene rubber in the ionomer resin.

摘要:
One memory cell region includes memory cells that are aligned in a first direction and a second direction orthogonal to the first direction, a word line contact region adjacent to the memory cell region in the first direction interposed by a dummy pattern region, and first and second word lines that span a plurality of active regions aligned in the first direction and extend from the memory cell region to the word line contact region. A first word line and a second word line adjacent to each other within one active region located in the memory cell region constitute a word line pair. A gap in the second direction between a first word line and a second word line that constitute a word line pair in the memory cell region is narrower than a gap in the second direction in the word line contact region.
