From The Free On-line Dictionary of Computing (18 March 2015) :

  parallel random-access machine
      (PRAM) An idealised parallel processor consisting
     of P processors, unbounded shared memory, and a common
     clock.  Each processor is a random-access machine (RAM)
     consisting of R registers, a program counter, and a
     read-only signature register.  Each RAM has an identical
     program, but the RAMs can branch to different parts of the
     program.  The RAMs execute the program synchronously one
     instruction in one clock cycle.
