Write assist

机译:写辅助

摘要

A circuit includes a core having a memory array. The memory array includes memory cells and bitlines, and is arranged in columns. The core includes a metallization layer having connections to the memory array, which is devoid of memory cells. Digit lines are connected to the bitlines of a column of the memory array. A write driver is connected to the digit lines. A write assist circuit is connected to the write driver. The write assist circuit maintains a voltage on the digit lines prior to write operations and provides a boost voltage to the digit lines during write operations. A wire bridge located in the metallization layer of the core connects the write assist circuit to the write driver.
