摘要:
In a semiconductor memory device, a printed circuit board connects a memory chip to an external circuit. The printed circuit board includes a multiplicity of pads arranged in a column. These pads connect the board to the memory chip. The board also includes a multiplicity of data terminals arranged in at least two columns and connected to the pads by data connections. The data connections are configured such that each data connection has essentially the same electrical properties as any other data connection.
