Abstract
An electronic memory array includes a plurality of memory domains, a current controller, and a selector device. Each memory domain includes a plurality of bit cells. The current controller includes a current controller output electrically connectable to said plurality of memory domains and is configured to control a bit cell current. The selector device is electrically connected to the current controller and the plurality of memory domains. The selector device is configured to selectively electrically connect the current controller output to only a select one of said memory domains, such that the current controller controls only the bit cell current of the bit cells of the select memory domain.
Claims7
An electronic memory array, comprising:
- a plurality of memory domains, each memory domain including a plurality of rows of bit cells and a plurality of columns of bit cells;
- a current controller including a current controller output electrically connectable to said plurality of memory domains and configured to control a bit cell current;
- and
- a selector device electrically connected to said current controller and said plurality of memory domains, said selector device configured to selectively electrically connect said current controller output to only a select one of said memory domains, such that said current controller controls only said bit cell current of said bit cells of said select memory domain,
- wherein said selector device includes a demultiplexer including a demultiplexer input electrically connected to said current controller output and a plurality of demultiplexer outputs,
- wherein each demultiplexer output is electrically connected to a corresponding one of said memory domains, and
- wherein each demultiplexer output is electrically connectable to each column of bit cells of said corresponding memory domain.
