The physical implementation of memory (that is, RAM, ROM, or content-addressable memory (CAM)) in a device. A memory segment contains a sequence of memory bits corresponding to an address range.
In all Altera devices supported by the Quartus® Prime Standard Edition software except MAX 3000 and MAX 7000 devices, a memory segment consists of a bit-slice of a memory that is implemented in a single embedded cell. Each embedded cell implements one output of the memory. Multiple memory segments may be needed to create a single memory block.
