| titleOfInvention | Dual port RAM test method |
| abstract | (57) [Abstract] [Purpose] Dual that allows testing of the presence or absence of a short circuit between the bit line of the first port and the bit line of the second port simultaneously with the presence or absence of a defect in the memory area such as so-called marching. A method for testing a port RAM is provided. [Structure] A memory area of a dual port RAM is initialized in an initialization step, writing to a first memory area and reading to a second memory area are simultaneously performed in a write / read step, and a first step is performed in a read step. The third memory area arranged at the intersection of the column where the memory area is arranged and the row where the second memory area is arranged is read, and the writing / reading step and the reading step are performed while sequentially changing the first memory area. Are alternately repeated, and the presence or absence of a short circuit between the bit line of the first port and the bit line of the second port is tested based on the data read in the reading step. |
