Primitive: 36K-bit Configurable Synchronous Block RAM
- PRIMITIVE_GROUP: BLOCKRAM
- PRIMITIVE_SUBGROUP: BRAM
Introduction
The RAMB36E5 allows access to the block RAM memory in the 36 Kb configuration. This element can be configured and used as a 9-bit wide by 4K deep to a 36-bit wide by 1K deep true dual port RAM. This element can also be configured as a 72-bit wide by 512 deep simple dual port RAM. Both read and write operations are fully synchronous to the supplied clock(s) to the component. However, the READ and WRITE ports can operate fully independent and asynchronous to each other, accessing the same memory array. When configured in the wider data width modes, byte-enable write operations are possible, and an optional output register can be used to reduce the clock-to-out times of the RAM. This RAM also features a cascade capability, which lets you chain multiple RAMB36E5 components to form deeper and more power efficient memory configurations if desired.

ECC Signals: Error Correction Circuitry ports | |||

CLKARDCLK | Input | 1 | Port A clock input/Read clock input. |
ENARDEN | Input | 1 | Port A RAM enable/read enable. For best power characteristics of this component, it is suggested to drive this pin Low whenever a new read or write operation is not necessary on port A. Significant power savings can be seen when this port is driven Low. |

SLEEP | Input | 1 | Dynamic shut down power saving. If SLEEP is High, the block is in power saving mode. If SLEEP_ASYNC=FALSE, synchronous to RDCLK, otherwise, asynchronous input. Using this pin can save additional power if the RAM is not accessed for sustained amounts of time. |
WEA<3:0> | Input | 4 | Port A byte-wide write enable. In the case that port A is write-only and byte-write operation is not necessary, it is suggested to connect all bits High and control write operation with the ENARDEN port. Doing this improves power consumption of the block RAM. In wide 72-bit mode or if port A is read-only or not used, tie all bits Low. In other modes, the connections are dependent on WRITE_WIDTH_A setting. See the Versal ACAP Memory Resources Architecture Manual (AM007) for WEA mapping for different port widths. |
Port A Data: Port A data signals. | |||

ENBWREN | Input | 1 | Port B RAM enable/Write enable. For best power characteristics of this component, it is suggested to drive this pin Low when ever a new read or write operation is not necessary on port B. Significant power savings can be seen when this port is driven Low. |
REGCEB | Input | 1 | Port B output register clock enable (valid only when DOB_REG=1 and READ_WIDTH≤36). |
RSTRAMB | Input | 1 | Synchronous data latch set/reset to value indicated by SRVAL_B. |
RSTREGB | Input | 1 | Synchronous output register set/reset to value indicated by SRVAL_B. RSTREGB sets/resets the output register when DO_REG=1. RSTREG_PRIORITY_B determines if this signal gets priority over REGCEB. Not used when READ_WIDTH=72. |
WEBWE<8:0> | Input | 9 | In the case that port B is write-only and byte-write operation is not necessary, it is suggested to connect all bits High and control write operation with the ENBWREN port. Doing this improves power consumption of the block RAM. When using ECC mode, all bits must be tied High. In the case that port B is read-only or not used, tie all bits Low. In other modes, the connections are dependent on WRITE_WIDTH_B setting. See the Versal ACAP Memory Resources Architecture Manual (AM007) for WEBWE mapping for different port widths. |

Programmable Inversion Attributes: Specifies whether or not to use the optional inversions on specific pins of this component to change the active polarity of the pin function. When set to 1 on a clock pin (WRCLK or RDCLK), this components clocks on the negative edge. When set to 1 on other pins, it changes the function to behave active-Low rather than active-High. For pins that are buses, the bit-width of this attribute should match that of the bit-width of the associated pins and a binary value indicates which inverters to use and which to bypass. If an external inverter is specified on one of these associated pins, the Vivado Design Suite will automatically set this attribute during the opt_design stage so that additional logic is not necessary for changing the input polarity. | ||||

RST_MODE_A, RST_MODE_B: Specifies if the user reset signal is synchronous (SYNC) or asynchronous (ASYNC). The default value is SYNC, which means the RSTRAM or RSTREG (if output registers are used) to a specified SRVAL.

The SRVAL setting is also ignored. | ||||
