the company's "XtraROM" HybridFlash technology
应该也是一种Flash ROM,我上面也提到不少Flash ROM也声称室温保存20年,
NS卡带的技术对比之下是能更耐高温,也许室温的保存时间也能更长一些。
到Macronix官网看了一下,不能简单分类成Flash ROM,毕竟用词也是Hybridflash,
Macronix官网能看到他们是有做Mask ROM的,我一开始还猜测是不是基于Mask ROM的技术。
然后搜索到在国外论坛看别人讨论提到:
According to Kilguss, HybridFlash consists of XtraROM, flash memory and controller, which can respectively serve OS storage, boot loader/code update, and interface purposes.
确实有部分是直接用了Flash。
还提到了跟SLC NAND和MLC NAND的对比:
Compared to SLC NAND flash or MLC synchronous NAND flash, XtraROM performs better in Random Read, Sequential Write, Random Write, and Read Cycle.
这个人发言最后猜测XtraROM技术基础还是Flash ROM:
in the end, it seems that Macronix's "XtraROM" chips are not really Mask-ROM chips afterall, but merely a different kind of Flash Memory technology developed proprietorially at Macronix's R&D labs, and as such it would most likely be susceptible to Data-Rot as well, just like any other flash memory would to date.
我个人认为XtraROM技术是混杂了Mask ROM和Flash ROM的技术,因为提到技术优势的时候有提到Mask烧录的样子。
Mask ROM是生产的时候使用Mask(光掩膜)只能一次性写入数据不能修改、进行大批量生产,也符合游戏卡带的使用场景需求,用了Mask ROM的技术也正常。
