Abstract
A memory has an array of memory cells, column logic, a write driver, a voltage detector, and a bootstrap circuit. The array of memory cells is coupled to pairs of bit lines and word lines. The column logic is coupled to the array and is for coupling a selected pair of bit lines to a pair of data lines. The write driver is coupled to the pair of data lines. The voltage detector provides an initiate boost signal when a voltage of a first data line of the pair of data lines drops below a first level during the writing of the pair of data lines by the write driver. The bootstrap circuit reduces the voltage of the first data line in response to the boost enable signal. This is particularly beneficial when the number of memory cells on a bit line can vary significantly as in a compiler.
