Patent ID: 6862203

Claim:
A semiconductor memory with shielding effect, comprising: a plurality of word lines which are parallel to each other; a ground line control unit; and a plurality of memory units, each memory unit comprising: a primary bit line which physically crosses the word lines perpendicularly, and the primary bit line is enabled by a control signal; a ground line which is electrically connected to the ground line control unit, and is parallel to the primary bit line; a first equivalent switch; and a second equivalent switch; wherein the first equivalent switch of the n th memory unit of the memory units is coupled to both the primary bit line of the n th memory unit and the ground line of the n th memory unit, and the first equivalent switch is controlled by the control signal of the (n-1) th memory unit; wherein the second equivalent switch of n th memory unit of the memory units is coupled to both the primary bit line of the n th memory unit and the ground line of the (n+1) th memory unit, and the second equivalent switch is controlled by the control signal of the (n+1) th memory unit; wherein n is positive integer.
