Title: Semiconductor storage
Inventor: KATO TOMOAKI
IPC: G11C11/413
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To generate a necessary timing signal, regardless of the change of the number of noises or bits by laying a negative logic dummy word line in parallel to and near a dummy word line, inputting a signal to the end of the dummy word line from a dummy work driver and outputting the inputted signal to one of both ends of the negative logic dummy word line. SOLUTION: A negative logic dummy word line *DWORD is laid in parallel to and near a dummy word line DWORD. An inverter 1 inputs the signal received from a dummy word driver through the end of the line DWORD, that is laid opposite to the supply source of the signal received from the dummy word driver. The delay is attained by a stray capacity C, existing between both lines DWORD and *DWORD and the number of control load elements, and each size of these elements can be reduced. Meanwhile, the load value is controlled to the line DWORD, in response to the increment or decrement of the number of bits per word, and a proper delay is obtained.
