Abstract:
In a static random access memory cell having a gating field effect transistor of a first type and an associated storage field effect transistor of the first type, the improvement comprising:the gating field effect transistor having a first gate insulation layer with a relatively small gate insulation layer capacitance, the first gate insulation layer occupying a first surface area within the static random access memory cell, andthe storage field effect transistor having a second gate insulation layer with a relatively large gate insulation layer capacitance for substantially reducing charge flow from the storage field effect transistor during a read operation, thereby substantially reducing an inadvertent state change in the static random access memory cell during the read operation, the second gate insulation layer occupying a second surface area within the static random access memory cell, where the first surface area substantially equals the second surface area.
