Integrated circuit comprising at least two memories

摘要

An integrated circuit includes a first and second memory, with the first memory being configurable between a first data format and a second data format. An external address bus is connected to the second memory, and an internal bus is connected to the first memory. A rerouting circuit is connected between the external address bus and the internal bus. The rerouting circuit forms one of two connections between the external address bus and the internal bus dependent upon the configuration of the first memory.
