Abstract
A pseudo dual-port memory device is disclosed. One embodiment provides an internal data RAM for a microprocessor, and a method for operating a memory device. In one embodiment, a memory device for a microprocessor or microcontroller comprises: a first part with memory cells that are single-port memory cells; and a second part with memory cells that are dual-port memory cells. In another embodiment, a method for operating a memory device is provided, the memory device including at least one single-port memory and at least one dual-port memory, the method including: accessing the single-port memory of the memory device when a non-conflicting access is to be carried out at the memory device; and accessing the dual-port memory of the memory device when a conflicting access is to be carried out at the memory device.
