    Abstract: PURPOSE: A semiconductor memory device for performing a wafer test process using a high frequency is provided to check data bits received through data lines by using only one comparison circuit. CONSTITUTION: A semiconductor memory device for performing a wafer test process using a high frequency includes a memory cell array(1110), an address buffer circuit(1150), a test block signal generation portion(1160), a test clock signal generation portion(1180), a test data generation portion(1190), a test data write portion, a test data read portion, and a decision portion(1310). The memory cell array are used for storing data. The address buffer circuit is used for receiving an external address in response to a test clock signal. The test block signal generation portion generates a test block signal which is synchronized with the external clock signal in a test operation mode. The test clock signal generation portion generates a test clock signal according to the test block signal. The test data generation portion generates test data according to the test clock signal. The test data write portion writes the test data in a predetermined region of the memory cell array. The test data read portion reads the test data from the predetermined region of the memory cell array. The decision portion receives data bits and decides whether the data bits on the data lines have the same value, or not. The decision portion outputs a flag signal as a decided result.

    Abstract: PURPOSE: A power on reset circuit is provided, which detects the supply of an external power supply voltage(EXTVDD) accurately without regard to an increase rate of the external power supply voltage. CONSTITUTION: A differential amplifier(120) senses a voltage difference between the first input port and the second input port, and generates an output signal. The first voltage generator supplies the first voltage to the first input port of the above differential amplifier. The second voltage generator supplies the second voltage to the second input port of the differential amplifier. The first voltage generator generates the first voltage using a power supply voltage supplied from the external, and the second voltage generator generates the second voltage using an internal power supply voltage, converted from the power supply voltage supplied from the external.

    Abstract: A semiconductor memory device generates a test clock signal (whose periods and cycle number are variable) having a shorter cycle than that of an external clock signal, and internally test data using the test clock signal. The semiconductor memory device may repeatedly perform read/write operations using the internally generated test clock signal during a half cycle of the external clock signal. By comparing output data in the read operation with known data, a test apparatus may determine whether memory cells of a memory device are normal. In a low-frequency test apparatus, it is possible to screen disadvantages that may occur when a high-speed memory device operates at a high frequency.
