发明名称 Semiconductor memory testing device and method of testing semiconductor using the same
摘要 The semiconductor memory testing device includes a test signal decoder decoding burn-in test mode signals which generates a first test signal for use in controlling entire main wordlines and which generates a second test signal for use in controlling sub wordlines. When the first and second test signals are in an disabled state, the semiconductor memory testing device also includes a plurality of bank control units generating a multi wordline test mode signal as a multi wordline test signal corresponding to a bank control signal, and simultaneously enabling a plurality of wordlines in accordance to the multi wordline test signal to perform a test. The semiconductor memory testing device reduces a testing time and current consumption and thus enhances a more stable voltage drop when performing continuous multi wordline test on a per bank basis.
