Title:
DYNAMIC BUS HAVING SINGLE CENTRAL PRECHARGE
Document Type and Number:
Japanese Patent JP3529548
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic bus system having a central precharging device which uses a control circuit provided with a one-shot generator and a write synchronizing circuit in combination with a logic output module having a pull-up/down device.
SOLUTION: The generation of an output enable(OE) signal is interlocked with the turning off of precharge. Therefore, the collision between buses can be avoided, because data are written on a dynamic bus 201 only when a precharging device is inactivated. Because of the resulted circuit, the precharge of the bus 201 is surely performed before the data are written on the bus 201 and, at the same time, a synchronizing OE signal can be generated in the same clock phase as that of a precharge signal.
