                2.3. Intel® Stratix® 10 HBM2 Features
   Intel® Stratix® 10 FPGAs offer the following HBM2 features. 
  
 
  - Supports one to eight HBM2 channels per HBM2 interface in the Pseudo Channel mode.
- Each HBM2 channel supports a 128-bit DDR data bus, with optional ECC support.
- Pseudo Channel mode divides each channel into two individual 64-bit I/O pseudo-channels. The two pseudo-channels operate semi-independently; they share the channel’s row and column command bus as well as CK and CKE inputs, but they decode and execute commands individually. Address BA4 directs commands to either pseudo-channel 0 (BA4 = 0) or pseudo-channel 1 (BA4 = 1), offering unique address space to each pseudo-channel. Pseudo Channel mode requires that the burst length for DRAM transactions is set to 4.
- Data referenced to strobes RDQS_t / RDQS_c and WDQS_t / WDQS_c, one strobe pair per 32 DQs.
- Differential clock inputs (CK_t / CK_c). Unterminated data/address/cmd/clk interfaces.
- DDR commands entered on each positive CK_t and CK_c edge. Row Activate commands require two memory cycles; all other command are single-cycle commands.
- Supports command, write data and read data parity.
- Support for bank grouping.
- Support for data bus inversion.
- 64-bit data per pseudo-channel. Eight additional data bits are available per pseudo-channel; you can use these data bits for any of the following: 
     - ECC. The ECC scheme implemented is single-bit error correction with double-bit error detection (SECDEC). This includes 8 bits of ECC code (also known as syndrome).
- Data mask (DM). The data mask for masking write data per byte.
- Can be left unused.
 
- I/O voltage of 1.2V and DRAM core voltage of 1.2V.
