  • Patent number: 5610862
    Abstract: According to the present invention, a method and structure for using pre-charged data path techniques in those applications where it is necessary to retain the previous state of data is presented. In the preferred embodiment, a Pre-Charged Slave Latch with Parallel Previous State Memory circuit of a burst SRAM employs a parallel memory element configuration. In conjunction with this parallel memory element configuration, three stages are disclosed to implement a pre-charged data path technique for a burst SRAM memory. First, external data is loaded into the Pre-Charged Slave Latch with Parallel Previous State Memory circuit. Next, during a burst address sequence state of the Burst SRAM, the previous address state is allowed to propagate through the address decode path of the burst SRAM. Finally, the output signal of the Pre-Charged Slave Latch with Parallel Previous State Memory is pre-charged to an inactive state in parallel with other circuit elements of the pre-charged address decode path.
