    摘要: A static random-access memory (SRAM) comprises multi-port storage cells with built-in column-interleave selection circuitry which allow a storage cell to be written to via a plurality of different write paths. Column selects are built into each storage cell by adding an additional isolating switch between the storage node of the storage cell and the bitline of a particular write path in order to prevent a cell write from affecting other storage cells connected to the same wordline in the same interleaved array. The write data bus corresponding to each write path for all interleaved cells are shared by all storage cells in a common interleave group, and each adjacent pair of storage cells in a common row share bitlines coupled to the common data bus, resulting in smaller number of required bitlines.

    摘要: During read operations of a column of RAM cells, a bitline is electrically broken into two sections. This reduces the capacitance that needs to be discharged by the RAM cell itself. A buffer is used during the read operation to relay data from one part of the split bitline to the other. A weak pullup path is also provided to hold the non-driven end of the line in a stable condition. During non-read operations, the two sections of bitline are electrically connected.
