I have been reading about XD/NX bit used in Memory Pages for security. I understand it is a security feature that can help reduce system exposure to viruses and malicious code. If enabled, processor prevents the execution of code in data-o… Continue reading XD/NX Bit in UNIX [Memory Security]
There’s a longstanding belief that when someone loses one ability, another improves correspondingly. New research bears this out – in one scenario, at least – as it indicates that blind people remember spoken information better than their sighted count… Continue reading Study suggests blind people excel at memorizing spoken information
Researchers in Japan have developed a new method for making 5-cm (2-in) wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data – the equivalent of one billion Blu-Ray… Continue reading Two-inch diamond wafers could store a billion Blu-Ray’s worth of data
Computer memory is a problem that has been solved for many years. But early on, it was more than just a small problem. We’ve many of the different kinds at …read more Continue reading Hard(er) Drives: Impractical, Slow, Amazing, and Incredible
When running Windows Memory Diagnostic, if you receive a black screen or blue screen either after…

Is it possible to inject code into RAM using physical access? For example desolder the RAM chips, solder something between the original RAM chip and the phone motherboard, and use that to directly access RAM chip content and inject code in… Continue reading Is it possible to inject code using physical memory access to jailbreak phones?
Computer memory has taken on many forms over the years, from mercury-based delay-line tubes to handwoven magnetic core. These days, volatile storage using semiconductors has become ubiquitous with computing, but …read more Continue reading Glow In The Dark Computer Memory Illuminates The Fundamentals
Every time one of us flashes an Arduino’s internal memory, a nagging thought in the backs of our minds reminds us that, although everything in life is impermanent, nonvolatile re-writable …read more Continue reading Stress-Testing An Arduino’s EEPROM
Scientists continue to illuminate the many ways exercise can positively influence brain health by examining its effects on the many forms of cognitive function, and the latest places a spotlight on our ability to recall past experiences. The results of… Continue reading Aerobic exercise found to boost episodic memory as we get older
Sounds like somebody had a really bad day at work, as Western Digital reports that “factory contamination” caused a batch of flash memory chips to be spoiled. How much, you …read more Continue reading Hackaday Links: February 20, 2022
