摘要： Memory bank selection control circuits and methods are provided which improve the data sensing margin for data sense amplifiers in a multi-bank semiconductor memory structure. In one aspect, a bank selection signal control circuit includes a bank switch control unit that receives memory bank selection signals and outputs corresponding memory bank selection control signals to selectively connect memory banks to a global data input/output line according to a predetermined sequence. For memory bank selected prior to a last selected memory bank in the predetermined sequence, the bank switch control unit outputs memory bank selection control signals that are enabled for a first time period P1, and for the last selected memory bank, the bank switch control unit outputs a memory bank selection control signal that is enabled for a second time period P2, wherein P2 is greater than P1. A switching unit sequentially connects each selected memory bank to the global data input/output line according to the predetermined sequence, and for a predetermined period P1 or P2, in response to the corresponding bank selection control signals.

摘要： A semiconductor memory system, a memory control circuit and a semiconductor memory device are disclosed. The system includes a memory control circuit for generating a data strobe signal and a data load signal in synchronization with each other. The memory circuit, which can be an SDRAM memory circuit, receives the data strobe signal and the data load signal and writes data in response to the two synchronous signals. Because the signal are synchronous, parameters introduced by timing variations caused by different signal domains are eliminated. As a result, high-frequency operation of the system is greatly improved.

摘要： A system and method allows for multiple modes of termination, including termination by a fixed value that is preprogrammed, and by a variable value that can, for example, be measured and determined by a self-calibration circuit. Multiple termination values can be achieved within a single device. This configuration is especially applicable to devices that have different loadings for address and data signals, for example in a configuration having a common, shared address bus, and multiple, localized data buses.

摘要： A first clock signal is processed to produce a second clock signal that lags the first clock signal by a first predetermined time and a third clock signal that leads the first clock signal by a second predetermined time. A synchronous read status signal generator circuit receives a read initiation signal indicative of initiation of a read operation and a read termination signal indicative of termination of the read operation. The synchronous read status signal generator circuit produces a transition in a read status signal in response to assertion of either of the read initiation signal or the read termination signal, and latches the read status signal responsive to the second clock signal to generate a synchronized read status signal. A latency signal generator circuit receives the synchronized read status signal and generates a latency control signal therefrom responsive to the third clock signal. Output of data from the memory device is controlled responsive to the latency control signal.

摘要： An MML integrated circuit device includes a memory block, a logic circuit and a buffer memory, and a selection circuit that is coupled between the logic circuit and the buffer memory. The first selection portion is responsive to external data and to the logic circuit, to transmit external data or data from the logic circuit to the memory block via the buffer memory. Thus, MML integrated circuit devices can use the buffer memory to access the memory block during a normal operational mode and during a test mode. MML integrated circuit devices also preferably include a data expansion portion that is coupled between the external data and the selection portion, to replicate the external data a predetermined number of times and to transmit the replicated external data to the selection portion. Errors may be detected in an MML integrated circuit device that includes a memory block, a logic circuit and a buffer memory, by storing external data from external of the MML integrated circuit device into the buffer memory, and storing the external data from the buffer memory into the memory block. The external data is read from the memory block and the read external data is stored from the memory block into the buffer memory. The read external data is output from the buffer memory to external of the MML integrated circuit device. The external data may be stored from external of the MML integrated circuit device into the buffer memory by applying external data from external of the MML integrated circuit device to the MML integrated circuit device, replicating the external data a predetermined number of times in the MML integrated circuit device and storing the replicated external data in the buffer memory.

摘要： A bitline sense amplifier includes a pre-sensing unit and an amplification unit. The pre-sensing unit is connected to a first bitline and a second bitline, and is configured to perform a pre-sensing operation by controlling a voltage level of the second bitline based on at least one pre-sensing voltage and variation of a voltage level of the first bitline. The amplification unit is configured to perform a main amplification operation by amplifying a pre-sensed voltage difference based on a first voltage signal and a second voltage signal. The pre-sensed voltage difference indicates a difference between the voltage level of the first bitline and the voltage level of the second bitline after the pre-sensing operation.
