Theory: 4-byte error code EDC: In the CD-ROM sector, there is a 4-byte 32-bit EDC domain, which is used to store the CRC code. The CRC verification code of the CD-ROM generates a polynomial of 32th order, p (x) = (x16 + x15 + X2 + 1) (x16 + X2 + x + 1 ). The data block used to calculate the CRC code is the Data byte from the beginning of the slice to the end of the user data zone. Take mode1 as an example,

OpenSSL promises to inform developers of sandbags in advance when a problem occurs. In view of the recent hetbleed vulnerability, the OpenSSL Project decided that the Linux and Unix operating system publishers who use the popular OpenSSL encryption package will be notified in advance when OpenSSL releases security-related fixes. The OpenSSL Project determines that the operating system issuer with OpenSSL receives a notification before the rectificatio

Microsoft said that the security vendors that receive this treatment must meet two requirements: one is to develop security software for the Windows platform, and the other is that the software must have a large user scale. According to foreign media reports, Microsoft recently announced that it will inform some security software companies of the security patch content that Microsoft will release starting in March. This aims to allow security so

, each NAND memory block is deleted less frequently within a given period of time.Bit SwitchingAll flash devices are plagued by bit switching. In some cases (rarely, Nand occurs more often than nor), a bit is reversed or reported to be reversed.One-bit changes may not be obvious, but if it occurs on a critical file, this small fault may cause system downtime. If there is only a report problem, it may be solved by reading multiple times.Of course, if this bit changes, you must use the error detec

I,Introduction to NAND/nor flashNor and NAND are two major non-loss flash technologies on the market. Intel first developed nor Flash technology in 1988, which completely changed the previous situation where EPROM and EEPROM were integrated. Next, in 1989, Toshiba published the NAND Flash structure, emphasizing reducing the cost per bit, providing higher performance, and easily upgrading through interfaces like disks. Its capacity can reach more than 1 GB, And the write and erase speed is very f
