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.
