Abstract
A local bit switch selecting circuit and method for systems having a first number of banks of sense amplifiers with a second number of sense amplifiers in each sense amplifier bank. The bit switch selecting circuit and method use a single N channel field effect transistor in each sense amplifier bank. This provides bit switch selecting capability while significantly reducing the number of devices and chip area required.
