Abstract: A method for detecting a half-full condition of a first-in, first-out memory array. The method of the invention includes the steps of a) moving a write pointer through the array to write data to alternating rows of the memory array; b) moving a read pointer through the array to read data from the alternating rows of the memory array in first-in, first-out order; and c) providing a half-full indication when the read pointer and the write pointer point to adjacent rows in the memory array. This method eliminates the need to route lines across the array to detect a half-full condition, thereby reducing die and power requirements and offering an increase in speed.

Abstract: A FIFO memory system organizes a memory with N word storage locations into M pointer-based random access memories, each containing N/M storage locations. A sequence of data words is written into and read out of the M RAMs in a cyclical fashion. An M fold increase in write rate is obtained by an input control logic which causes all M RAMs to be in a different stage of the shift-in cycle at the same time. Similarly, an M fold increase in read rate is obtained by an output control logic which causes all M RAMs to be simultaneously in a different stage of the shift-out cycle. The output signals of the RAMs being read are multiplexed to generate the original sequence.

Abstract: An emitter coupled logic circuit includes a bypass circuit which provides a conductive path for current when a programmable fuse is blown, so that input data is transmitted independently of the state of a clock signal. In one implementation, the circuit takes a register configuration having a master section and a slave section, each incorporating a programmable fuse. When the fuse in just one section is intact, the circuit serves as a clocked latch. When both fuses are blown, the bypass circuit is enabled so that the register functions as a combinatorial circuit which produces an output signal dependent on the input signal without reference to a clock signal.
