signal. The output registers can be bypassed. Pseudo-asynchronous
reading is possible in the simple dual-port mode of M4K blocks by
clocking the read enable and read address registers on the negative clock
edge and bypassing the output registers.
When configured as RAM or ROM, you can use an initialization file to
pre-load the memory contents.
Two single-port memory blocks can be implemented in a single M4K
block as long as each of the two independent block sizes is equal to or less
than half of the M4K block size.
The Quartus II software automatically implements larger memory by
combining multiple M4K memory blocks. For example, two 256

16-bit
RAM blocks can be combined to form a 256
×
32-bit RAM block. Memory
performance does not degrade for memory blocks using the maximum
number of words allowed. Logical memory blocks using less than the
maximum number of words use physical blocks in parallel, eliminating
any external control logic that would increase delays. To create a larger
high-speed memory block, the Quartus II software automatically
combines memory blocks with LE control logic.
Parity Bit Support
The M4K blocks support a parity bit for each byte. The parity bit, along
with internal LE logic, can implement parity checking for error detection
to ensure data integrity. You can also use parity-size data words to store
user-specified control bits. Byte enables are also available for data input
masking during write operations.
Shift Register Support
You can configure M4K memory blocks to implement shift registers for
DSP applications such as pseudo-random number generators, multi-
channel filtering, auto-correlation, and cross-correlation functions. These
and other DSP applications require local data storage, traditionally
implemented with standard flip-flops, which can quickly consume many
logic cells and routing resources for large shift registers. A more efficient
alternative is to use embedded memory as a shift register block, which
saves logic cell and routing resources and provides a more efficient
implementation with the dedicated circuitry.
