In one embodiment a low voltage high performance memory system is
disclosed. The system can include a bit cell, a first pass gate coupled
to the bit cell to receive a write signal, a second pass gate coupled to
the bit cell to receive the write signal, and an supply current
controller to reduce current to at least a portion of the bit cell and to
supply current to another portion of the cell in response to a write
control signal and a data signal during a bit cell transition. Reducing
the current to a portion of the bit cell and supplying current to another
portion of the bit cell during transition can allow the bit cell to
transition to a different state faster and can reduce the effects of
device variations that manifest during low voltage operation. Other
embodiments are also disclosed.
