Abstract
A serial access memory has multiple memory blocks, each with a row-and-column array of memory cells for storing data. Data access is synchronized with a clock signal. A column address counter counts the clock signal to generate a column address. A block selector decodes upper bits of the column address to generate a series of block select signals, which are distributed to the memory blocks. In each memory block a shift register receives and shifts one block select signal to generate a series of column select signals.
