概要
説明
The 4MX0121V is a 12-bit bus switch/multiplexer (MUX) designed for 2.5V supply voltage operation. The MUX is designed for operation in DDR3 and DDR4 memory bus systems. The 4MX0121V has a 1:2 switch or 2:1 multiplex topology with a 12-bit wide bus.
The 4MX0121V uses a high-speed switch architecture providing high bandwidth, low insertion loss, return loss, and very low propagation delay, allowing for the use in many applications requiring switching or multiplexing of high-speed signals.
特長
- Host controller bus isolation from the DRAM memory during "save" and "restore" operations between DRAM and NVDIMM non-volatile memory
- AC and DC parameters optimized for DDR4, enabling the highest possible memory channel performance for NVDIMMs even when intermixed with other DIMM types
- 12-bit bus switch/multiplexer to best match the eight DQ pins and four DQS pins coming from each DRAM
- VFBGA 48-pin package for a compact footprint that can replace data buffers on the DIMM for NVMDIMM applications
- Make-before-break circuit to prevent glitches during switching operations

How DDR4 LRDIMMs Transcend RDIMMs in Today's Enterprise Servers
A white paper authored by IDT (acquired by Renesas) and Micron details research into memory and bandwidth for today's high-performance servers. LRDIMMS and RDIMMS traditionally have been seen as complementary, with the former targeting applications requiring deeper memory and the latter for applications requiring higher bandwidth.
The introduction of 8-gigabit DRAMS has resulted in a growing number of Internet applications benefiting from both deeper memories and higher bandwidth. This paper shows how 32 GB 2RX4 LRDIMMs transcend similar RDIMMs to meet the needs of today’s data center enterprise servers, by providing an optimal combination of deeper memory and higher data bandwidth, even at mainstream module densities.
