Abstract: An interleaved memory includes an array of memory cells divided into a first bank of memory cells and a second bank of memory cells. The interleaved memory operates in a burst access mode. A first address counter is coupled to the first bank of memory cells, and an address register is coupled to the first address counter and to the second bank of memory cells. A timing circuit generates increment pulses to the first address counter so that a first random access asynchronous read cycle starts with the first bank of memory cells. A function of an address counter for the second bank of memory cells is being performed by coping contents of the first address counter to the address register.

Abstract: A method of synchronizing the start of sequential read cycles when reading data in a memory in a synchronous mode with sequential access uses the increment pulses as synchronization signals for the address counters of the memory cell array. Following each increment pulse, a dummy ATD pulse is generated. The dummy ATD pulse is undistinguishable from an ATD pulse generated upon detection of a switching of external address lines.

Abstract: A redundancy architecture for a memory includes an array of memory cells divided into at least a pair of semi-arrays that are singularly addressable. Each semi-array is organized into rows and columns. The redundancy architecture includes a number of packets each including redundancy columns. The packets are divided into two subsets of packets. Each packet is addressable independently from the other by respective address circuits. Each packet also provides redundancy columns exclusively for a respective semi-array.

Abstract: An address binary counter for an interleaved having an array of memory cells being divided into a first bank of memory cells and a second bank of memory cells includes as many stages as the bits that may be stored in the memory cells of a row of one of the banks, and a carry calculation network. The interleaved memory operates in a burst access mode enabled by an enabling signal. The carry calculation network includes an ordered group of independent carry generators. Each independent carry generator includes a certain number of stages, with each stage having inputs receiving its own enabling bit and a number of consecutive bits of a row of the bank equal to the number of stages, orderly starting from the least significant bit. The enabling bit of the first carry generator of the ordered group is the enabling signal, and the enabling bit of any other carry generator of the ordered group is the logic AND of the enabling signal and of the input bits of the preceding carry generator of the ordered group.

Abstract: An interleaved memory is readable in a sequential access synchronous mode and in a random access asynchronous mode based upon externally generated command signals including an address latch enabling signal and a chip enable signal. The memory includes a circuit for regenerating the externally generated address latch enabling signal. A first and a second internal replica signal are generated by the circuit. The second internal replica signal has a leading edge that is delayed with respect to a leading edge of the first internal replica signal. A duration of the second internal replica signal is conditionally incremented to prevent non-synchronization between the externally generated address latch enabling signal and the externally generated chip enable signal when the interleaved memory is operating in the sequential access synchronous mode or in the random access asynchronous mode.

Abstract: A control circuit manages transferring of data within a system, such as an interleaved memory. The system includes a plurality of data sources for providing an output data stream synchronous with an external timing signal, an output register for storing data available at an output of the system, and a selection multiplexer for transferring the data from the plurality of data sources to the output register. The control circuit includes a plurality of circuit blocks, with each circuit block being dedicated to one of the plurality of data sources. Each circuit block includes a detection circuit for detecting availability of the data at an output of a selected data source, and a conditioned update path connected to the detection circuit provides an update flag. A logic gate having a first input receives the update flag and a second input receives an output signal from the detection circuit for providing a selection signal for the selection multiplexer.
