这个例子来自被Intel Cap投资的Ayar Lab,正好也用到了本文前面讲的2.5D Chiplet的技术。左图是概念图,下面绿色的就是Package Substrate,中间是一个FPGA Die,边上Die是光I/O的Phy(TeraPHY)。FPGA Die和TeraPHY就是通过Intel的EMIB模式连接的(没有额外的Interposer)。右边就是最终的封装外形,可以看到,正是把光I/O...
Key Rambus HBM Gen2 PHY product highlights include support for DRAM 2, 4 and 8 stack height, a DFI-style interface to the memory controller, 2.5D interposer connections between the PHY and DRAM, a validated memory controller interface, support for wafer-level and interposer testing, as well ...
The HBM3 OPHY utilizes state-of-the-art architecture in full custom analog mixed-signal design to overcome the problem of long-term impedance drift and clock phase drift, allowing impedance and clock phase updates without the need to interrupt data traffic. The programmable timing PHY boundary com...
Using LPDDR5 across the whole range of its devices, like Apple does, has some additional benefits, such as LPDDR5 controller IP and PHY re-use in different SoCs as well as procuring such memory in high volumes, which gives a leverage to negotiation for better...
An HBM PHY can be verified at block level and test-chip level using this verification strategy. Some of the challenges and common issues mentioned will help in verification architecture planning and development. Most companies however are facing struggles with the verification of the ...
