Abstract
A highly integrated system-on-chip system with a non-volatile memory unit, includes a chip having an integrated MRAM memory unit, and semiconductor layers disposed underneath the MRAM memory unit and functioning merely as carriers for the MRAM memory unit. An integration density of the chip may be increased by using the semiconductor layers for additional integrated circuits.
Claims7
A chip, comprising:
- a semiconductor substrate;
- and
- an integrated circuit disposed above said semiconductor substrate;
- said integrated circuit containing an MRAM (Magnetoresistive Random Access Memory) memory unit having a memory cell field;
- and
- said integrated circuit containing parts implemented in said semiconductor substrate underneath said memory unit, and said parts containing additional memory units.
