    Abstract: A circuit arrangement for reading out data time delayed from a semiconductor memory comprises a common data input at which read data, which are read out of a semiconductor memory, are present and a data buffer FIFO for buffering the read data. The buffer FIFI comprises a plurality of FIFO modules each comprising a plurality of individual FIFO cells. Each FIFO module can be addressed via respective allocated first input and output pointers and each FIFO cell can be addressed via respective allocated second input and output pointers. The circuit arrangement further comprises a controllable read latency generator generating the first and second output pointers for driving the FIFO modules and FIFO cells with a read latency predetermined with reference to the first and second input pointers, respectively, and a common data output at which the read data are present time-delayed in dependence on the predetermined read latency.

    Abstract: A non-volatile memory wherein bad columns in the array of memory cells can be removed. Substitute redundant columns can replace the removed columns. Both of these processes are performed on the memory in a manner that is externally transparent and, consequently, need not be managed externally by the host or controller to which the memory is attached. The bad column can be maintained on the memory. At power up, the list of bad columns is used to fuse out the bad columns. The memory may also contain a number of redundant columns that can be used to replace the bad columns.

    Abstract: A semiconductor memory device comprises a memory cell array and a control circuit. The memory cell array has a plurality of memory cells arranged in rows and columns. The memory cells store data and are selected according to address signals. The control circuit is configured to receive a clock signal and a first control signal, and output a plurality of data in response to the clock signal after the first control signal is asserted. After the first control signal is asserted, an internal signal which responds to the clock signal transits N times (N is a positive integer and greater than or equal to 2), then output of the data is started. At least one of the data is output at the transition after the output begins.

    Abstract: Selecting circuits for columns of an array of memory cells are used to hold read data or write data of the memory cells. The memory cells may be multistate memory cells. There is a shift register chain, having a stage for columns of the array. A strobe pulse is shifted through this shift register. The strobe points, with each clock, at and enables a different selecting circuit in sequence. That particular selecting circuit that has been enabled by the strobe will then perform a certain function. In a read mode, the selected selecting circuit will send the stored information through to the output buffer for output from the integrated circuit. And while in a programming mode, the selected selecting circuit will receive data from an input buffer. This data will be written into a memory cell.
