METHOD FOR MINIMIZING THE ACCESS TIME FOR SEMICONDUCTOR MEMORIES

摘要

The dictates of production mean that the access times of semiconductor memories are subject to fluctuations, even given identical technological parameters. The fluctuations lead to a proportion of slow memory chips. The access time is shortened by raising the internal supply voltage of the slower semiconductor memories by an absolute value which is dependent on the respective semiconductor memory. The method is employed in semiconductor memories, in particular in dynamic semiconductor memories.
