Description

SK hynix Registered DDR4 SDRAM DIMMs (Registered Double Data Rate Synchronous DRAM Dual In-Line

Memory Modules) are low power, high-speed operation memory modules that use DDR4 SDRAM devices.

These Registered SDRAM DIMMs are intended for use as main memory when installed in systems such as

servers and workstations.

Features

• Power Supply: VDD=1.2V (1.14V to 1.26V)

• VDDQ = 1.2V (1.14V to 1.26V)

• VPP - 2.5V (2.375V to 2.75V)

• VDDSPD=2.25V to 2.75V

• Functionality and operations comply with the DDR4 SDRAM datasheet

• 16 internal banks

• Bank Grouping is applied, and CAS to CAS latency (tCCD_L, tCCD_S) for the banks in the same or dif-

ferent bank group accesses are available

• Data transfer rates: PC4-3200, PC4-2933, 2666, PC4-2400, PC4-2133, PC4-1866, PC4-1600

• Bi-Directional Differential Data Strobe

• 8 bit pre-fetch

• Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop)

• Supports ECC error correction and detection

• On-Die Termination (ODT)

• Temperature sensor with integrated SPD

• This product is in compliance with the RoHS directive.

• Per DRAM Addressability is supported

• Internal Vref DQ level generation is available

• Write CRC is supported at all speed grades

• DBI (Data Bus Inversion) is supported(x8)

• CA parity (Command/Address Parity) mode is supported
