  We consider Parallel Random Access Machine (PRAM) which has some processors
and memory cells faulty. The faults considered are static, i.e., once the
machine starts to operate, the operational/faulty status of PRAM components
does not change. We develop a deterministic simulation of a fully operational
PRAM on a similar faulty machine which has constant fractions of faults among
processors and memory cells. The simulating PRAM has $n$ processors and $m$
memory cells, and simulates a PRAM with $n$ processors and a constant fraction
of $m$ memory cells. The simulation is in two phases: it starts with
preprocessing, which is followed by the simulation proper performed in a
step-by-step fashion. Preprocessing is performed in time $O((\frac{m}{n}+ \log
n)\log n)$. The slowdown of a step-by-step part of the simulation is $O(\log
m)$.
