Write assist

A circuit, comprising:

• a core comprising a memory array, the memory array comprising memory cells having bitlines, the memory array being arranged in columns, wherein the core includes a metallization layer comprising connections to the memory array, and wherein the metallization layer is devoid of memory cells;
• digit lines connected to the bitlines of a column of the memory array;
• a write driver connected to the digit lines;
• and
• a write assist circuit connected to the write driver, wherein 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, and wherein a wire bridge located in the metallization layer of the core connects the write assist circuit to the write driver.
