Abstract

See full text

A semiconductor memory device and a method for accessing the same are disclosed. The semiconductor memory device comprises a memory transistor, a first control transistor and a second control transistor, wherein a source electrode and a gate electrode of the first control transistor are coupled to a first bit line and a first word line respectively, a drain electrode and a gate electrode of the second control transistor are coupled to a second word line and a second bit line respectively, a gate electrode of the memory transistor is coupled to a drain electrode of the first control transistor, a drain electrode of the memory transistor is coupled to a source electrode of the second control transistor, and a source electrode of the memory transistor is coupled to ground, and wherein the memory transistor exhibits a gate electrode-controlled memory characteristic. The semiconductor memory device increases integration level and decreases refresh frequency.
