Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor storage device in which the pull-out of charges from subword lines is conducted at a high speed and the generation of a leak condition of the threshold value voltage Vt of an access MOS transistor in a memory cell is prevented without increasing the chip size. SOLUTION: The connection of the source of a MOS transistor 104 and the drain of a MOS transistor 105 is carried out by connection to the signal line of address signals RA00. The connection of the source of a MOS transistor 104' and the drain of a MOS transistor 105' is carried out by connection to address signals RA02. Control signals RANE are inputted into the gate of a MOS transistor 108 and its drain is connected to the signal line of the address signals RA00 and its source is connected to a GND line. Each of the subword lines of the transistors 105 and 105' are connected to a GNDXDEC line and the transistors 105 and 105' are formed by a small gate width holding a ground potential. The MOS transistors 108 and 108' have a gate width from which a current capacity, that rapidly transitions the subword lines from a boosting potential to a ground potential, is obtained.

IPC: H04L12/70
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To generate highly accurate synchronizing clock signal at a low cost. SOLUTION: On the basis of the difference of the count values of a counter 102 stored in a capture circuit 103 at first and second times, the frequency of an internal clock signal K and the frequency of a reference clock signal M, a CPU 104 calculates the number of reference clock signals to be received between the first and second times and calculates the number of synchronizing clock signals to be generated while generating the reference clocks of the calculated number. Besides, the number of synchronizing clocks counted by a counter 106 between the first and second times is calculated and the frequency dividing ratio of a baud generator 105 is controlled to reduce the difference between the calculated number of synchronizing clock signals and the number of synchronizing clock signals.  Thus, a synchronizing clock signal B synchronized to the reference clock signal M can be provided from the baud generator 105.
