Figure 6-11.—64 × 64 array memory quadrant.
The sense line is threaded through all the cores in the
array. One 64 by 64 array forms one quadrant of a
memory plane.
Figure 6-11 is an illustration of a
64 × 64 array.
Memory Plane.—Each quadrant of a memory
plane (four in each memory plane) contains one bit
position of 4096 memory words. An example of a
memory plane is shown in figure 6-12. Each memory
plane will provide 4 bit positions (one for each
quadrant) over 4096 addresses when using 64 by 64
arrays. The memory plane is the basic building block
of the memory stack.
Memory Stack.—The memory stack contains all
the core of the device and the associated circuitry, which
includes the X and Y drive lines, inhibit lines, and sense
