Abstract
A system includes: a controller, a first memory module connected to the controller through a first data bus, and a second memory module connected to the controller through a second data bus, wherein the first memory module includes: first and second memory chips; a first data terminal connected to the first data bus, and a first switch unit that electrical connects the first data terminal with either the first memory chip and the second memory chip, and the second module includes: third and fourth memory chips; a second data terminal connected to the second data bus, and a second switch unit that switches over electrical connection of the second data terminal with either the third memory chip or the fourth memory chip.
Claims19
A system, comprising:
- a controller;
- a first memory module connected to the controller through a first data bus;
- and
- a second memory module connected to the controller through a second data bus that is electrically disconnected from the first data bus, wherein
- the first memory module comprises:
- a first memory chip and a second memory chip;
- a first data terminal connected to the first data bus;
- and
- a first switch unit that switches over electrical connection of the first data terminal with either the first memory chip or the second memory chip, and
- the second memory module comprises:
- a third memory chip and a fourth memory chip;
- a second data terminal connected to the second data bus;
- and
- a second switch unit that switches over electrical connection of the second data terminal with either the third memory chip or the fourth memory chip.
A memory module, in a system that includes a controller,
- wherein said memory module is included a first memory module connected to the controller through a first data bus, and a second memory module connected to the controller through a second data bus that is electrically disconnected from the first data bus, said memory module being the first memory module and comprising:
- a first memory chip and a second memory chip;
- a data terminal connected to the first data bus;
- and
- a switch unit that switches over electrical connection of the data terminal with either the first memory chip or the second memory chip.
