A bandwidth guaranteeing apparatus includes a controller that collects guaranteed communication rate for a plurality of devices on an OVC between a user-side apparatus and the bandwidth guaranteeing apparatus; and a determiner that obtains the smallest value of the guaranteed communication rate collected by the controller and upon a bandwidth change request that is for the OVC and from the user-side apparatus, determines whether the bandwidth change request can be accepted, based on the obtained guaranteed communication rate.

Bandwidth guaranteeing apparatus and bandwidth guaranteeing method

A pair of power supply lines that are orthogonal to the border with the cell array are placed, for each one-bit processing circuit of the data processing unit, in a semiconductor storage device such as SRAM or the like comprising a data processing unit for writing data to memory cells and reading it therefrom, a row decode unit for driving the word lines of the memory cells, and a timing control unit for generating a control pulse for the data processing unit, all of which are arranged around the circumference of a cell array in which memory cells are arrayed in a grid-like fashion. MOS transistors are placed between the power supply lines in such a position that the principal axis direction of the gate pattern is orthogonal to the two aforementioned wirings, and are closely arrayed in the longitudinal direction of the power supply lines.

Production method for semiconductor storage device and semiconductor storage device

A semiconductor device includes: a first circuit in which a diffusion area A, a first gate G, a diffusion area A, a second gate Gand a diffusion area Aconstitute two transistors; and a second circuit in which a diffusion area B, the first gate G, a diffusion area B, the second gate Gand a diffusion area Bconstitute two transistors. The diffusion areas Aand B, the diffusion areas Aand Band the diffusion areas Aand Bare connected. Alternatively, the diffusion areas A, Aand Band the diffusion areas A, Band Bare connected.
