Abstract
A dynamic random access memory circuit achieves much higher data bandwidth by maximizing the number of memory cell rows that are held open and by indefinitely increasing the time that the rows are open. The boosted voltage of a pump circuit is directed to active rows according to the presence of a pump token. The pump token is present at one location in a circular shift register corresponding to a memory array. The concurrence of the token and a pump-enable signal causes that array to receive a boosted voltage independent of an array-select operation.
