Abstract
Embodiments of the invention provide a memory arrangement having an even number k=4 of physically spaced RAM chips, on each of which it is possible for m data items to be simultaneously written or read via an m-bit data bus, also having a register for buffer-storing and transmitting n respective parallel data bits as a packet between an n-bit parallel port and the data buses, and having a selection device which responds to selection bits in order to select a respective separate cell group within the plurality of the chips for each of the disjoint m-bit groups (d) of the n-bit packet. The k chips are classified into q=2 disjoint chip groups, each of which comprises k/q chips which differ as little as possible from one another in terms of their distance from the register. The number m is chosen to be equal to q*n/k, and the selection device is designed to select a respective separate chip from the same chip group and a cell group in this chip for each m-bit group of the same n-bit packet.
