    • A semiconductor memory system is provided to transceive data between a memory controller and a memory device by using a half-duplex mode SERDES(SERializer/DESerializer) chip, and reduce skew between pins and a manufacturing cost by reducing the number of pins, as a half-duplex mode is applied. The memory device(300) transceives a signal with the memory controller(100). The SERDES chip(200) selectively provides a path between the memory controller and the memory device to perform transmission/reception through one I/O(Input/Output) pin. The SERDES chip includes an instruction interpreter(260) selectively providing a controller and memory transmitter enable signal by receiving an instruction from the memory controller, a read replica circuit(280), and a write replica circuit(270). The read replica circuit synchronizes a time point for transmitting the data to the memory controller by responding to the controller transmitter enable signal. The write replica circuit synchronizes the time point for transmitting the data to the memory device by responding to the memory transmitter enable signal.

    • PURPOSE: An input/output circuit and a current control circuit of a semiconductor memory device are provided to prevent leakage of current in a test mode such as a burn-in test by forming the input/output circuit and the current control circuit insensitive to a change of a fabrication process, a variation of a voltage level of an input/output pin, and a variation of temperature. CONSTITUTION: The first and the second transfer portions(33,34) are formed by CMOS transfer gates. The first transfer portion(33) transfers low voltage(VOL) of the first input/output pin(31) in response to a current control enable signal(CCE). The second transfer portion(34) transfers high voltage(VOH) of the second input/output pin(32) in response to the current control enable signal(CCE). A voltage distributor(35) generates a mean value of the low voltage(VOL) and the high voltage(VOH). A comparator(36) compares the mean value(Vcmp) with reference voltage(Vref). A current control counter(37) generates control bits(ICTR0-ICTR5) in response to an output of the comparator(36). Resistances(R33,R34) of the first and the second transfer portions(33,34) are used for preventing leakage of current.

    • PURPOSE: An audio data access method of a memory using a parity bit is provided to search a damaged bit in a memory device and store and read a certain audio data without a damaged bit. CONSTITUTION: An audio data which will be stored in a memory is temporarily stored in a data storing register(S11). a parity generator generates and combines a parity bit(S12) and applies to the memory and stored therein(S13). When the audio data is stored, the stored data is read(S14), and the parity search unit searches a parity bit and judges whether an error occurs. If an error occurred, an address is increased(S16). The routine is returned to S13. If an error does not occur, the stored audio data is continuously stored(S17), and an address is increased. In the case that the audio data is stored in the memory, a parity bit is combined with the audio data. It is judged whether an error occurs by reading a stored corresponding data. If the error does not occur, the address is stored, and if the error occurs, the audio data I stored into the next address, and it is checked whether an error occurs. When reading the audio data stored in the memory, the audio data stored in the memory(S21) is read and is temporarily stored in the data read register, and a parity is searched(S22) for thereby judging whether an error occurs. If the error does not occur, it is judged that the audio data is normally stored.
