Integrated circuit equipment and system using said equipment

Abstract

Provided are an integrated circuit device having two or more ports and a system for the device, where the device includes a first port for inputting and outputting data and a second port for inputting the data, and either the first port and / or the second port is selected by an external command when the data is input; the second port has 1 / 2 n the number of pins of the first port, where n is a natural number; the device includes two or more ports that operate independently so that turn around time is reduced and the data bus efficiency of the integrated circuit device and the system are improved.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 2002-55682 filed with the Korean Industrial Property Office on September 13, 2002 (Attorney Docket No. SS-17922). technical field [0003] The present invention relates to an integrated circuit device, in particular to an integrated circuit device with two or more input ports, wherein each port can work independently. Background technique [0004] As the operating frequency of the interface of the integrated circuit device, especially the storage device, increases, the efficiency of the bus decreases relatively. A typical storage device usually has input / output ports for inputting and outputting data. In such a typical memory device, bus efficiency decreases due to an increase in operating frequency. [0005] Although some memory devices have separate input ports and separate output ports, the input ports and output ports are completely separated from ...

Problems solved by technology

[0011] like figure 1 and figure 2 As shown, as the operating frequency of the integrated circuit device increases, the turnaround time required for going from a read operation to a write operation and back increases, and vice versa, thus, the efficiency of the data bus decreases
