Abstract
A one-shot signal generation circuit is provided which makes it easy to adjust pulse width and to deal with variation of skew of an ATD signal, and can reduce chip area. A timing determination section ( ) is reset by an edge of a first detected signal among a plurality of address transition detection signals (ATD signals) which have arrived within the skew period of an address signal, measures a first predetermined time by taking an edge of a second detected signal as start instant, and outputs a signal DST which reflects the result of this measurement. A timing determination section ( ) measures a second predetermined time by taking an edge of the first detected signal as start instant, and outputs a signal PG which reflects the result of this measurement. An LC generation circuit ( ) outputs a one-shot signal (LC) whose start instant is determined by the signal PG and whose end instant is determined by the signal DST.
