A low-voltage contact-programming mask ROM was designed which utilizes a cascode sense amplifier (S/A). A dummy S/A controls the bit-line pre-charging period to operate the read S/A quickly in spite of high programmed-data-dependence of the bit-line capacitance. The word-line has branches to enhance the cell current with little increase in area. A demonstrated 4 K/spl times/8 bit ROM operates with an access time of 5.7 ns and power of 2.2 mW at 1.0 V, 100 MHz, and 25/spl deg/C.","PeriodicalId":433264,"journal":{"name":"1999 Symposium on VLSI Circuits.

The method takes every silicon atom in the device into account and is generally applicable to arbitrary nonuniform doping profiles. In addition to body dopant fluctuations, the effect of source-drain dopant fluctuations on short-channel threshold voltage is studied for the first time. The result clearly indicates the benefit of retrograde body doping and shallow/abrupt source-drain junctions. It also quantifies the magnitude of threshold voltage variations due to discrete dopant fluctuations in an optimally designed 25 nm MOSFET.","PeriodicalId":433264,"journal":{"name":"1999 Symposium on VLSI Circuits.

Recently there has been a growing interest in ferroelectric RAM because of its great potential as a future nonvolatile memory.
