Abstract
A random access memory includes a memory array of storage cells arranged in addressable rows and columns. A serial register is coupled to the memory array and to a serial register address decoder. A serial counter generates and applies to the serial register address decoder a sequence of addresses starting with an initial tap address. In response to the initial tap address, a first data bit is read out of an addressed storage cell of the memory array and is applied to a first input of a multiplexer. The initial tap address either is passed to the serial register address decoder or is incremented and applied to the serial register addressed decoder for accessing a second data bit from the serial register to a multiplexer. The initial tap address is incremented before passage only if the least significant bit of the initial address is odd.
