ABSTRACT:
The invention relates to a multiport-RAM memory device, comprising a RAM memory unit (1), a number of serial/parallel converters (5, 6, 7) and a parallel/serial converter (10), for converting serial signals into parallel signals. Said multiport-RAM memory device further comprises a control unit (11) and two timeslot allocation devices (8, 9), whereby an emulation of a number of connections by using the simple RAM memory unit (1) may be achieved. Furthermore, a power controller (12) can significantly reduce the power demand.
