Semiconductor integrated circuit having pads layout for increasing signal integrity and reducing chip size

摘要

A semiconductor integrated circuit device includes a semiconductor chip having a memory cell array region surrounded with a peripheral circuit region and includes a plurality of bonding pads disposed at least in one row on only one side of the semiconductor chip. The circuit device may include first leads group disposed adjacent to the bonding pad side and a second leads group disposed opposite the first leads group. The second leads group may be formed over a portion of the semiconductor chip (lead-on-chip structure). A plurality of bonding wires connect the first and second leads group with the plurality of bonding pads respectively.
