摘要： A temperature information outputting circuit of a semiconductor memory apparatus for accurately performing a temperature measuring test is presented. The temperature information outputting circuit includes first, second and third temperature information outputting units. The first temperature information outputting unit outputs a first temperature information signal to a single temperature information outputting pad when a first test signal is enabled. The second temperature information outputting unit stores a second temperature information signal when the first test signal is enabled and outputs the stored second temperature information signal to the single temperature information outputting pad when a second test signal is enabled. The third temperature information outputting unit stores a third temperature information signal when the first test signal is enabled and outputs the stored third temperature information signal to the single temperature information outputting pad when a third test signal is enabled.

摘要： A periodic signal generating circuit which is dependent upon temperature for establishing a temperature independent refresh frequency is presented The periodic signal generating circuit includes a reference voltage generating unit and a periodic signal generating unit. The reference voltage generating unit produces a reference voltage which exhibits a variable voltage level in response to temperature. The periodic signal generating unit produces a periodic signal in response to a set voltage to determine the reference voltage and an oscillation period, wherein a transition timing of the set voltage is controlled by the reference voltage. As a result the periodic signal has a relatively constant period which can be produced regardless of the temperature variation.
