Abstract
Circuits and methods to minimize power required for sensing and precharge of DRAMs have been achieved. A control circuit ensures that during READ operations the duration of sensing of DRAM cell and precharging is kept to a minimum. A test DRAM cell is used to determine the exact time required for data sensing. Furthermore no precharging is performed during WRITE-operations. In case data is changing from '1' to '0' or vice versa data lines are inverted accordingly during WRITE operation.
