Abstract
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.
Claims4
An integrated memory chip, comprising:
- an external control terminal;
- a dynamic memory;
- a control circuit for controlling a memory access to said dynamic memory;
- and
- an external address terminal;
- said control circuit having an input connected to said external control terminal, for receiving an access command indicating a beginning of a memory access;
- and
- said control circuit having an output connected to said dynamic memory, for outputting at least one signal generated from the access command and selected from the group consisting of an activation signal, a read command or write command, and a precharge command;
- said dynamic memory having word lines and bit lines;
- said control circuit having an address terminal for receiving an address for the memory access;
- said external address terminal connected to said address terminal of said control circuit;
- and
- said control circuit for generating, from a received address, respective column addresses and row addresses for access to said word lines and said bit lines of said dynamic memory.
