2011 IEEE International Solid-State Circuits Conference, 2011•ieeexplore.ieee.orgIn this study, the authors propose a new offset tolerant current-sampling-based SA (CSB-SA)
to achieve 7x faster read speed than previous SAs for sensing small ICELL. A fabricated
90nm 512Kb OTP macro, using the CSB-SA and our CMOS-logic compatible OTP cell,
achieves 26ns macro random access time for reading sub-200nA lCELL. Measurements
also confirmed that this 90nm CSB-SA could achieve sub-100nA sensing.
