Mode in which if RAS is kept low and the DRAM is given a column address without being given a new row-address, the chip will remember which row it was on the last time and automatically stay on that row. It is like saying that all the bits along one row are all on the same page, and the part will assume the same page is intended until a different page is specified.
A bit added to a group of bits to detect the presence of an error. The parity bit looks at the other 8 bits and determines if they are even or odd and correspondingly is a 0 or 1. The system compares the 8 bits with the parity bit. If they both are even or odd, the data is assumed to be correct. If one is even and one is odd, there is an error, and typically the system will fail.
A device incapable of current gain or switching, such as a resistor or capacitor.
Printed circuit board. Board that contains layers of circuitry that is used to connect components to a system.
Personal Computer Memory Card International Association. An industry organization that helps to set standards for flash cards.
See Presence Detect.
Programmed input/output is a method of transferring data between the CPU and a peripheral such as a network adapter or an ATA storage device.
A PCB with components
