Abstract:
A static random access memory cell, comprising:a bit line;an access transistor electrically connected to the bit line;a pull down transistor;a first thin film transistor having a gate coupled to a first voltage through a load device comprising a second thin film transistor and to a second voltage different from the first voltage through the pull down transistor;a storage node coupled to the bit line through the access transistor, to the pull down transistor gate and to the first voltage through the first thin film transistor;the first thin film transistor having a gate formed in a first conductive structure and a source and drain formed in a second conductive structure, the second conductive structure extending coextensively relative to at least a portion of the first conductive structure;the second thin film transistor having a gate formed in the second conductive structure and a source and drain formed in the first conductive structure; anda dielectric between the first and second conductive structures.
