  • Patent number: 8970236
    Abstract: An internal voltage generating circuit is utilized to perform a TDBI (Test During Burn-in) operation for a semiconductor device. The internal voltage generating circuit produces an internal voltage at a high voltage level, as an internal voltage, in not only a standby section but also in an active section in response to a test operation signal activated in a test operation. Accordingly, dropping of the internal voltage in the standby section of the test operation and failure due to open or short circuiting are prevented. As a result, reliability of the semiconductor chip, by preventing the generation of latch-up caused by breakdown of internal circuits, is assured.
