  Memory B cell - Wikipedia, the free encyclopedia
Memory B cells are a B cell sub-type that are formed following primary infection.
When a B cell is activated, by recognizing a specific antigen, it proliferates to form antibody producing plasma cells and long-lived memory cells.
The memory B cells are specific for the antigen that first stimulated their production.

 Visualizing Memory Hierarchies
Typically, a memory hierarchy works as follows: when a memory location is accessed, its contents are placed into the highest level of the memory hierarchy, with the hope that the contents of the memory location will be accessed again in a short period of time.
One feature of the memory cell history display is to allow the quick selection of interesting periods of time, which can in turn be used jump to an interesting time on one of the dynamic displays.
Memory cells are colored to reflect the total number of misses seen, with light red shades indicating a few misses and dark red shades indicating many misses.

 How memory works
DRAM Memory is arranged in a XY grid pattern of rows and columns.
When a memory location is written to, a hardware parity generator generates a parity bit that is stored in an extra memory chip.
One limiting factor is the memory cell where stray capacitance in data lines slows the bus down - so look for the trend to a system module where the RAM die and processor are paced in a cartridge as is the Pentium II is with it's cache memory.

 Princeton, HP Labs demo plastic write-once memory | InfoWorld | News | 2003-11-13 | By Tom Krazit, IDG News Service
Researchers at the Princeton, New Jersey school and Palo Alto, California-based company, were able to develop a write-once memory cell that can hold gigabytes of information and be produced very inexpensively from a commonly used plastic substance and a small amount of silicon, they said.
Flash memory, like PEDOT-based memory, is nonvolatile, which means it can store information without the constant electrical charge required by RAM in PCs, he said.
A memory cube could be formed from small slivers of the PEDOT material, and the researchers envision being able to pack 1GB of information into one cubic centimeter, they said.

The circuit diagram of the single SRAM cell was shown in the specifications part and the working was also explained there.
The chip is mostly populated by SRAM cells; therefore we have put a significant effort into minimizing the cell.
It is evident from the size of the cell that we have succeeded0 - the overall memory array takes about 335.0* 970.0 (mm), leaving us a LOT of space for other circuitry.

The DMD is a memory chip covered with hinged, microscopic electromechanical mirrors, one for each pixel on the screen.
The state of each memory bit (0 or 1) in the video frame causes the mirror to tilt one way and direct light to a lens aimed at the screen or tilt the other way to deflect it.
The state of the memory cell (0 or 1) tilts the mirror to reflect or cancel light.
