In the field of semiconductor storage,DRAM high-performance memory is the key to the operation efficiency of electronic equipment.The DDR4 SDRAM products launched by our company strictly follow the JEDEC standard,and provide stable and reliable memory solutions for various high-performance computing scenarios with advanced architecture design and excellent electrical performance.

 

　　This series of DDR4 SDRAM adopts 8n prefetching architecture and integrates 16 banks(divided into 4 bank groups,each group contains 4 banks).This structure cooperates with the interface design of double data transmission per clock cycle to realize efficient data throughput.The read-write operation is carried out in burst mode,and the burst length of 8 or 4 is supported.By activating the command and selecting the address of the column and column,the storage unit can be accurately located.DRAM products support 1.2V core voltage and 2.5V auxiliary voltage,which ensures high-speed operation and optimizes power consumption performance.

 

　　Application advantages of DRAM high performance memory DDR4 SDRAM

 

　　①DRAM supports 1200/1333MHz clock rate,and cooperates with bidirectional differential data gating and differential clock input to ensure signal integrity.

 

　　②Programmable CAS delay,additional delay and write delay to meet the timing requirements of different master platforms.

 

　　③DRAM has built-in command address parity check and data bus write CRC check,which effectively improves the accuracy of data transmission.

 

　　④DRAM supports auto-refresh,auto-refresh,auto-refresh with low power consumption and maximum power saving mode,and can dynamically adjust energy consumption according to system load.

 

　　In terms of temperature adaptability,DDR4 SDRAM products cover the working range from 0℃to 95℃,and the shortened refresh period of 3.9 microseconds is adopted in the range from 85℃to 95℃to ensure the data retention ability in high temperature environment.The 78-ball FBGA package meets the requirements of lead-free and halogen-free environmental protection,and supports advanced functions such as on-chip terminal impedance calibration,write equalization and MPR reading training,which simplifies the system-level signal debugging.

 

　　DRAM products also integrate perfect initialization and reset mechanisms,supporting asynchronous reset and flexible configuration of DLL.Through the functions of soft repair and hard repair,the failure of storage unit after packaging can be effectively handled,and the yield and long-term reliability of finished products can be improved.For industrial control,network communication and consumer electronics fields that need DRAM high-performance memory,this series of DDR4 SDRAM provides a high-quality choice with balanced performance,power consumption and cost.
