摘要： A read register and a data transfer circuit are provided to implement two separate data transfer paths with respect to a preamplifier, for alternately transferring data through these two paths. Thus, the data can be transferred with no data collision in each clock cycle. The data are transferred at a high speed every clock cycle regardless of the bank number and the CAS latency in a multi-bank synchronous memory device.

摘要： A reset signal generating circuit in a synchronous semiconductor memory device outputs a reset signal ZPOR1 in response to a power on reset signal ZPOR generated immediately after power on and an initialize command (for example, a precharge command) executed for initialization after power on. A test mode register included in a mode setting circuit receives as a reset signal, the reset signal ZPOR1. Consequently, a test mode signal output attains to an NOP state, or output of the test mode signal is stopped.

摘要： A plurality of memory banks are activated to select a memory cell in response to a bank select signal from a bank select signal generating circuit. When a special mode of operation is designated, a mode setting circuit activates all of bank select signals from the bank select signal generating circuit to simultaneously drive all memory banks to active/inactive state. Thus, a multi-bank, a synchronous semiconductor memory device capable of accessing memory cells at high speed and efficiently selecting memory cells is obtained.

摘要： A semiconductor memory device includes a memory cell array (1) having a plurality of memory cells arranged in rows and columns, a plurality of column select lines (3) extending over the memory cell array and coupled to received column select signals generated by a column decoder (100), a plurality of power supply lines (4) provided in parallel with the column select lines to transfer a power supply voltage from a main power supply line (130), and a plurality of ground lines (5) provided in parallel with the column select lines to transfer a ground voltage from a main ground line. A plurality of fuse elements (6) are provided for each of the column select lines. When a short-circuit is found between a column select line and power supply line or a ground line, a fuse element corresponding to the short-circuited column select line is blown off and the short-circuited column select line is isolated from the column decoder. By repairing the short-circuited column select line with a redundant column select line (60), the memory device operates correctly without an adverse effect of the short-circuit.

摘要： An act signal generation circuit in a synchronous semiconductor memory device includes an act command latch circuit, an act command output circuit, and an act command control circuit. The act command latch circuit latches externally applied active command information. The act command output circuit responds to an enable signal to output an act initiation signal that renders a bank active. The act command control circuit responds to level transition of an external control signal in a test mode to alter the level of the enable signal. As a result, the active command information can be delayed and then transmitted to a bank.
