DIMM connector accomodating sideband signals for battery status and/or control
View Patent ↗A DIMM connector, including pins for transmitting side band signals for at least one of battery status or control for a battery backed cache is disclosed.
1. A DIMM connector, including:
a first plurality of pins connected to circuitry on a DIMM; and
a second plurality of pins having a dedicated connection to a battery status signal or a battery-backed cache control signal.
2. The DIMM connector of claim 1 , wherein the battery status signal indicates battery life.
3. The DIMM connector of claim 1 , wherein the second plurality of pins include at least one of:
a pin that communicates a signal indicating the presence of a battery backed memory module;
a pin that communicates a signal indicative of battery life;
a pin that communicates a signal indicative of non-volatile memory control; and
a pin that communicates a signal indicative of a battery power mode.
4. A cache card, including:
a DIMM connector comprising a first plurality of pins connected to circuitry on the cache card and a second plurality of pins dedicated for use to transmit a battery status or a battery-backed cache control signal.
5. The cache card of claim 4 , wherein the battery status signals indicates battery life.
6. The cache card of claim 4 , wherein the second plurality of pins includes at least one of:
a pin that communicates a signal indicating the presence of a battery backed memory module;
a pin that communicates a signal indicative of battery life;
a pin that communicates a signal indicative of non-volatile memory control; and
a pin that communicates a signal indicative of non-volatile memory control.
7. The DIMM connector of claim 1 , wherein the second plurality of pins include:
a pin that communicates a signal indicating the presence of a battery backed memory module;
a pin that communicates a signal indicative of battery life;
a pin that communicates a signal indicative of non-volatile memory control; and
a pin that communicates a signal indicative of a battery power mode.
8. The DIMM connector of claim 1 wherein at least one of the second plurality of pins is used by a host system to which the DIMM connector mates to determine whether other of said second plurality of pins are to be used to transmit a battery status or a battery-backed cache control signal, or whether such other signals are unconnected or used for a purpose other than the transmission of a battery status or a battery-backed cache control signal.
9. The cache card of claim 4 , wherein the second plurality of pins include:
a pin that communicates a signal indicating the presence of a battery backed memory module;
a pin that communicates a signal indicative of battery life;
a pin that communicates a signal indicative of non-volatile memory control; and
a pin that communicates a signal indicative of a battery power mode.
10. The cache card of claim 4 wherein at least one of the second plurality of pins is used by a host system to which the cache card mates to determine whether other of said second plurality of pins are to be used to transmit a battery status or a battery-backed cache control signal, or whether such other signals are unconnected or used for a purpose other than the transmission of a battery status or a battery-backed cache control signal.
