摘要： A system generates memory unit designs tailored to requirements. The system receives a set of specifications for one or more memory units. The set of specifications includes the memory type, the number of memory access ports, and the data width. The system assembles a memory unit schematic from a library of schematic modules defining memory unit components, including memory cells, address decoders, registers, drivers, sense amplifiers, and optionally self-testing components. The system creates a layout for the memory unit from a library of layout modules corresponding to the library of schematic modules. The library of layout modules includes memory unit floorplans specifying the location of layout modules within a memory unit. The system selects from different memory unit floorplans to create an optimized memory unit layout. The memory unit schematic can be validated using functional testing methods. The system processes the memory unit layout to produce a device configuration.

摘要： In mask programmable integrated circuit, such as a structured ASIC, a delay chain provides a delay that is set by a mask programmable switch. The delay chain receives an input to allow the delay mask programmed delay to be overridden using a JTAG controller. This allows testing of different delays. The input may also be provided by a fuse block, so that the fuse block can override the mask programmable switch, thus allowing a delay to be changes after mask programming.

An embodiment of the disclosed memory circuits includes a first memory block coupled to a second memory block to form an array of memory blocks. Each of the memory blocks has multiple bit lines with a dedicated address decoder coupled to the bit lines from each of the memory blocks. Switches are placed in between the first and second memory blocks such that each of the bit lines from the first memory block is connected to a corresponding bitline from the second memory block through one of the switches. The switches may be used to either connect the second memory block to the first memory block or disconnect the second memory block from the first memory block.

摘要： Dual port memory blocks that have a reduced layout area are provided. The write drivers and sense amplifiers are shared between the dual ports to reduce the number of write drivers and sense amplifiers to save layout area. The write drivers for the two ports are used to write into all of the first port's bitlines. The sense amplifiers for the two ports are used to read from all of the second port's bitlines. A memory block can to support true dual port (TDP) and simple dual port (SDP) operation using substantially less write drivers and sense amplifiers.

摘要： A memory unit includes width decoding logic enabling data to be accessed in a memory array at different data widths. To improve memory access speed, the memory unit also includes dedicated read output paths for accessing data at the full data width of the memory array. The dedicated read output paths bypass the width decoding logic and provide data from the memory array directly to a data bus, thereby providing improved memory performance when width decoding is not needed. The memory unit can be incorporated in programmable devices and a programmable device configuration can select either the read bypass paths or the width decoding logic. Hardware applications that require width decoding and improved memory access speed can utilize additional programmable device resources outside the memory unit to register the full width data from the memory unit and convert it to a different data width.
