Abstract:
A method of testing a memory device, comprising:activating equilibration between a digit line and a complement digit line; deactivating sense amplifiers; determining if a memory cell is a memory cell associated with a target word line; coupling the memory cell to an associated one of the digit line or the complement digit line if the memory cell is not the memory cell associated with the target word line; repeating determining if other memory cells are the memory cell associated with the target word line and coupling the other memory cells to their associated one of the digit line or the complement digit line until the mcmory cell associated with the target word line is determined; deactivating equilibration between the digit line and the complement digit line before coupling the memory cell associated with the target word line to its associated one of the digit line or complement digit line; and activating the sense amplifiers while the memory cell associated with the target word line and any other memory cells are coupled to their associated one of the digit line or complement digit line.
