Abstract
A semiconductor device includes a memory circuit, a first FIFO, a second FIFO and an input/output circuit. The memory circuit outputs data. The first FIFO receives data from the memory circuit and outputs data synchronously with a first clock signal. The second FIFO receives data output from the first FIFO and outputs data synchronously with the first clock signal. The input/output circuit outputs data output from the second FIFO. The second FIFO is disposed in the vicinity of the input/output circuit than the first FIFO.
Claims13
A semiconductor device comprising:
- a memory circuit configured to output data;
- a first FIFO configured to receive data from the memory circuit, and output data synchronously with a first clock signal;
- a second FIFO configured to receive data output from the first FIFO, and output data synchronously with the first clock signal;
- a third FIFO configured to receive data output from the first FIFO, and output data synchronously with the first clock signal;
- a signal circuit configured to receive the first clock signal;
- a first input/output circuit configured to output first data output from the second FIFO;
- and
- a second input/output circuit configured to output second data output from the third FIFO,
- wherein the signal circuit includes a pad sandwiched by the first input/output circuit and the second input/output circuit in a first direction.
