Abstract

During read operations of a column of RAM cells, a bitline is electrically broken into two sections. This reduces the capacitance that needs to be discharged by the RAM cell itself. A buffer is used during the read operation to relay data from one part of the split bitline to the other. A weak pullup path is also provided to hold the non-driven end of the line in a stable condition. During non-read operations, the two sections of bitline are electrically connected.
