Latest Patents

Inaba holds a patent for a "Semiconductor memory and testing method of same." This invention involves the use of column switches for sense amplifiers, which are selectively activated based on a column address. This design connects the sense amplifiers to a common data line. A sense amplifier control circuit is responsible for activating a sense amplifier activation signal to operate the sense amplifiers. During the test mode, the control circuit adjusts the time interval from the activation of a word line to the activation of the sense amplifier activation signal according to the column address. This ensures that the time interval after data is read from a test target memory cell until the corresponding sense amplifier begins its amplifying operation remains constant, regardless of the memory cell's position. As a result, consistent test conditions can be established for memory cells, allowing for accurate evaluation of their operational margins.
