摘要:
A FIFO memory is provided with individual arrays of dynamic memory cells and includes a dedicated write line buffer memory and a dedicated read line buffer memory operably connected thereto. First and second line buffer memories are also provided in conjunction with the write line buffer memory and the read line buffer memory so as to permit a faster response to the input and output of data with respect to the FIFO memory. Data may be alternately written into either one of the line buffer memories as a lead-in to the subsequent writing of data in the dynamic memory arrays via the write line buffer memory. Data read out from the other line buffer memory may occur simultaneously. The FIFO memory may serve as a video data frame memory for storing a frame of a video screen image. Where video data is continuously written into the FIFO memory, either the preceding video data frame or the current video data frame that is being written is subject to read out depending on the timing of a read reset signal relative to the last write reset signal. The write line buffer memory and the read line buffer memory are operable independently of each other, and may have simultaneous cycle times without any synchronization therebetween. The first and second line buffer memories preferably comprise static type memory elements to facilitate rapid data read out therefrom in response to a read reset signal.

An integrated circuit containing memory includes IEEE 1149.1 (JTAG) controlled self-repair system that permits permanent repair of the memory after the integrated circuit has been packaged. The JTAG controlled self-repair system allows a user to direct circuitry to blow fuses using an externally supplied voltage to electrically couple or isolate components to permanently repair a memory location with JTAG standard TMS and TCK signals. The system may optionally sequentially repair more than one memory location using a repair sequencer.
