    摘要: An anti-fuse memory cell having a variable thickness gate oxide. The variable thickness gate oxide has a thick gate oxide portion and a thin gate oxide portion, where the thing gate oxide portion has at least one dimension less than a minimum feature size of a process technology. The thin gate oxide can be rectangular in shape or triangular in shape. The anti-fuse transistor can be used in a two-transistor memory cell having an access transistor with a gate oxide substantially identical in thickness to the thick gate oxide of the variable thickness gate oxide of the anti-fuse transistor.

    摘要: Methods for testing unprogrammed single transistor and two transistor anti-fuse memory cells include testing for connections of the cells to a bitline by comparing a voltage characteristic of a bitline connected to the cell under test to a reference bitline having a predetermined voltage characteristic. Some methods can use test cells having an access transistor identically configured to the access transistor of a normal memory cell, but omitting the anti-fuse device found in the normal memory cell, for testing the presence of a connection of the normal memory cell to the bitline. Such a test cell can be used in a further test for determining the level of capacitive coupling of the wordline voltage to the bitlines relative to that of a normal memory cell under test.
