Extend PIC Microcontroller‘s RAM by without using EMI

Leave a Comment / Using Pic Microcontroller / By

Introduction Virtually all PIC microcontrollers have some banking mechanism to extend addressing to additional memory space. But this external data memory is not directly addressable (except in some high versions of PIC18 devices, which include PIC18F8520, PIC18F6620, etc.). In this post we describe easy to implement external memory interface for PIC microcontrollers. Theoretically most of …

Inside Intel’s first product: the 3101 RAM chip held just 64 bits

Leave a Comment / Tech News Updates / By

Intel’s first product was not a processor, but a memory chip: the 31011 RAM chip, released in April 1969. This chip held just 64 bits of data (equivalent to 8 letters or 16 digits) and had the steep price tag of $99.50.2 The chip’s capacity was way too small to replace core memory, the dominant …

The New Fujitsu ReRam

Leave a Comment / Tech News Updates / By

Resistive random-access memory (RRAM or Re RAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a dielectric solid-state material often referred to as a memristor. Fujitsu Semiconductor has just launched world’s largest density 4 Mbit Re RAM product for mass production: MB85AS4MT. Partnering with Panasonic Semiconductor Solutions, …
