Memory module for simultaneously providing at least one secure and at least one non-secure memory area

The module (230) has two write/read electronic units (132, 162) for two memory areas (133, 163), and an analog circuit part (234) for the write/read electronic units and the memory areas. The analog circuit part comprises a power supply circuit for supplying power to the write/read electronic units and the memory areas, where the module comprises a common interface unit (231) for connecting the write/read electronic units. The memory areas are designed as flash memory regions, and the analog circuit part comprises a charge pump and a write/read amplifier bank. An independent claim is also included for a microcontroller comprising a CPU.
