In a semiconductor memory device, a printed circuit board connects a memory chip to an external circuit. The printed circuit board includes a multiplicity of pads arranged in a column. These pads connect the board to the memory chip. The board also includes a multiplicity of data terminals arranged in at least two columns and connected to the pads by data connections. The data connections are configured such that each data connection has essentially the same electrical properties as any other data connection.

In order to operate an integrated dynamic memory having a memory cell array having bit lines and word lines a plurality of individual actions—to be performed for a memory access—from the activation of one of the word lines up to the precharging of the word lines are controlled in a synchronized manner with a clock signal. A value for defining a defined number of clock cycles between at least two individual actions is programmed at the beginning. For this purpose, a control circuit has a programmable unit. In this way, in conjunction with a clocked circuit, a comparatively high data throughput is made possible even at variable clock frequencies.

The invention provides a semiconductor memory device that includes at least two memory banks. The semiconductor memory device is designed in such a way that: at least two processor units can carry out read accesses and write accesses to memory banks; and by means of an inhibit command communicated by one of the processor units, the write access by the processor unit which has communicated the inhibit command and/or by at least one of the other processor units to the inhibited memory bank is prevented at least occasionally. A circuit arrangement including the above semiconductor memory device is furthermore proposed.

The integrated memory chip has an external control terminal, a dynamic memory, and a control circuit for controlling a memory access to the dynamic memory. The control circuit is connected to the external control terminal, for receiving an access command indicating the beginning of a memory access. The control circuit further has an output, which is connected to the dynamic memory, for outputting at least one activation signal, read command or write command and precharge command generated from the access command. This makes it possible, in the case of use in a data processing system, to dispense with a DRAM controller provided outside the memory chip.
