Samsung patents memory chip with one-time data storage section
Samsung describes a memory device that combines standard data storage with a special section called an antifuse cell array. This section uses transistors that can be programmed once to hold permanent data, which is then read by a specific amplifier circuit.
In the filing’s own words
The present disclosure relates to memory devices. An example memory device includes a memory cell region including a memory cell array is configured to store data, and an antifuse cell array including a plurality of antifuse bit lines, a plurality of antifuse word lines, and a plurality of program transistors that is electrically coupled to a first antifuse bit line among the plurality of antifuse bit lines and that are coupled in parallel with one another. The memory device includes a peripheral circuit region including an antifuse sense amplifier is configured to output one-time programmable (OTP) data stored in the plurality of program transistors.
What exactly they claim (claim 1)
1. A memory device comprising: a memory cell region including: a memory cell array that is configured to store data, and an antifuse cell array including (i) a plurality of antifuse bit lines, (ii) a plurality of antifuse word lines, and (iii) a plurality of program transistors that are electrically coupled to a first antifuse bit line among the plurality of antifuse bit lines and that are coupled in parallel with one another; and a peripheral circuit region, the peripheral circuit region including an antifuse sense amplifier that is configured to output one-time programmable (OTP) data stored in the plurality of program transistors.
