ABSTRACT:
A memory device having banks of sense amplifiers comprising two types of sense amplifiers. A first driver used to activate the first type of sense amplifier is embedded into a first bank. A second driver used to activate a second type of sense amplifier is embedded into a second bank. This alternating physical placement of the first and second sense amplifier drivers within respective banks is repeated throughout the device. This alternating physical arrangement frees up the gaps and mini-gaps for other functions, reduces the buses used for sense amplifier activation signals and allows large drivers to be used, which improves the operation of the sense amplifiers and the device itself.
