Abstract
A semiconductor device including a FIFO circuit in which a data capacity can be increased while minimizing an increase in a circuit scale is provided. The semiconductor device includes a single-port type storage unit (11) which stores data, a flip-flop (12) which temporarily stores write data (FIFO input) or read data (FIFO output) of the storage unit (11), and a control unit (14, 40) which controls a write timing of a data signal, which is stored in the flip-flop (12), to the storage unit (11) or a read timing of the data signal from the storage unit to avoid an overlap between a write operation and a read operation in the storage unit (11).
Claims4
A semiconductor device comprising:
- a single-port type storage unit which stores data;
- a flip-flop which temporarily stores write data or read data of the storage unit;
- and
- a control unit which controls a write timing of a data signal stored in the flip-flop to the storage unit or a read timing of the data signal from the storage unit to avoid an overlap between a write operation and a read operation in the storage unit.
Dependencies are inferred from the claim text.
