• Further reduction in power consumption
The default voltage of DDR2 memory is 1.8V, and the default voltage of DDR3 memory is only 1.5V, so the power consumption of memory is smaller and the calorific value is correspondingly reduced. It is worth mentioning that DDR3 memory also added temperature monitoring, the use of ASR (Automatic Self-refresh) design, by monitoring the te

DDR2DDR2 (double data rate 2) SDRAM is a new generation of memory technology standard developed by JEDEC (Joint Committee for electronic equipment engineering). The biggest difference between it and the previous generation of DDR memory technology standards is that, although the same basic method of data transmission is adopted at the same time as the clock increase/decrease delay, DDR2 memory has twi
addition to some motherboards also need to do in the BIOS settings, General motherboard specifications will be described. When the system has implemented dual-channel, some motherboards will be prompted at post, you can take a closer look. Since the self-test is faster, it may not be visible. So you can use some software to view, many software can check, such as cpu-z, relatively small. In the term "memory" there is a "channels" project, if the word "Dual" is shown here, it means that two chann

At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit
1 Introduction
DDR2 (double data rate2) SDRAM is a new generation memory technical standard developed by JEDEC (Joint Committee for electronic equipment engineering). It is the biggest difference from the previous generation of DDR memory technical standards: although the basic method of transmitting data at the same time with the clock rising/falling edge, DDR2 has twice the DDR pre-read capability (that
At present, we use the main computer memory is DDR3 memory, DDR4 memory is already in the research and development phase, has been successful, predicted 2014 total mass production instead of DDR3 memory, today, a netizen asked the editor such a question: the difference between DDR2 and DDR3? Why now DDR2 memory is more expensive than DDR3, which is good? If we compare DDR3 with
Ddr2/ddr II (Double Data Rate 2) SDRAM is a new generation of memory technology standards developed by the JEDEC (Joint Commission on Electronic Equipment Engineering), the biggest difference from the previous generation of DDR memory technology standards, although it was adopted in the rise of the clock/ The basic way of data transfer at the same time, but DDR2 memory has twice times the previous generatio
Nowadays, in FPGA system design, the complexity of the system is getting higher and higher, and the requirements for memory are getting higher and higher. Generally, DDR2 has become the first choice for FPGA systems considering the overall volume and capacity. Here, we will make a summary of the DDR2 design for the cyclone IV series FPGA. The FPGA and DDR Design for other series are similar.

The speed is soaring! AMD's AM2 Interface K8 architecture Processor introduced support for the highest DDR2 800, and Intel released its long-awaited Conroe processor on July 23 and carried out the largest "terrorist attack" in history, and the computer market appeared to have entered the DDR2 800 in 2006 ahead of time. RD600 supports 1500Mhz front-end bus overclocking,

1. Burst Length (BURSTLENGTH,BL)
Due to the DDR3 8bit, the burst transmission cycle (BURSTLENGTH,BL) is also fixed to 8, and for DDR2 and early DDR architecture system, BL=4 is also commonly used, DDR3 to add a 4bitBurstChop (sudden mutation) mode, That is, a bl=4 read operation combined with a bl=4 write operation to synthesize a bl=8 data burst transmission, then can control this burst mode by A12 address line. It should also be noted that any burs
