DDR5
Key Features
- On-Die ECC detects and corrects errors before data is sent to the CPU.
- Dual Subchannels on a DIMM. Two 40-bit-wide channels (32 data bits and 8 ECC bits) improve memory access.
- Longer Burst Length. DDR5’s burst length of 16 doubles that of DDR4, allowing access to 64 bytes of data with a single burst and using just one of two independent channels (half a DIMM), translating to better efficiency.
- Dual Data Rate (DDR) on command and address interface, as opposed to Single Data Rate (SDR) on command and address interface with DDR4, have freed up additional pins for isolation enhancements.
- Client Clock Driver (CKD) enables DDR5 CUDIMMs and CSODIMMs operating at up to 7200 MT/s or higher.
Description
ATP's DDR5 solutions outperform DDR4 in every way, delivering faster performance, higher memory bandwidth, higher densities,and improved power efficiency. This new-generation DRAM specification meets the growing memory needs of present and futurecritical computing applications.
Both DDR4 and DDR5 DIMMs have 288 pins, but DDR5 can transmit data faster with its higher bandwidth.
DDR5 modules will not fit in DDR4 sockets due to different alignment keys and pinouts that accommodate the new features.
