DDR5 Memory Modules
●DDR5 also improves scaling performance without degrading channel efficiency at higher speeds. This increased performance is achieved by doubling the burst length to BL16 and bank-count to 32 from 16. For increased reliability and efficiency, a DDR5 DIMM boasts two 40-bit fully independent sub-channels on the same module. DDR5 memory modules have a maximum die density of 64Gb and hence are capable of having a much higher DIMM storage capacity
●Features
■Command/Address and Control bus is double data rate
■Generates CRC checksum in READ data frames
■Default burst length increased to BL16 – Single burst = 64B of data
■Integrated Temperature Sensor (MR4)
■DDR5 DRAM contain 256 mode register
●Benefits
■Higher Bandwidth, DDR5 initial designs 4800 MHz
■Lower Power
■Better power efficiency and scalability
■Higher memory efficiency, lower latency
■Higher capacity DIMMs
●Applications
■High Performance Computing
■Cloud Computing and Storage
■Enterprise Networking
