摘要: A memory arrangement includes a plurality of memory blocks, a first group of access ports, and a second group of access ports. Routing circuitry couples each pair of the first and second groups of access ports to a respective one of the memory blocks. Each pair includes a first access port from the first group and a second access port from the second group. The first access port has write access to a first portion of the respective memory blocks but not to a second portion of the memory block, and has read access to the second portion but not to the first portion. The second access port has write access to the second portion but not to the first portion, and has read access to the first portion but not to the second portion.
