# main.py
# This program plots the conductance distribution of multiple MRAM cells on a 
# bit-line based on:
# [1] Rp (resistance-parallel) mean and variance
# [2] Rap (resistance-anti-parallel) mean and variance
# [3] number of MRAM cells on a bit-line
# note that we assume the random variables of each MRAM have the same 
# but independent distribution
