Bit inversion in memory devices

A method of transferring a data stream, comprising:

• directly receiving a data stream and an inversion flag associated with the data stream from an external data source device into a different device, wherein each device includes its own storage and processing capabilities, and wherein the data stream remains unchanged in the external data source even when an inversion flag has been set for the data stream in the external data source, and wherein the inversion flag is part of bytes housed in a register where each bit identifies a single unique data stream;
• transferring one or more bits associated with the data stream from the external data source device to a target source, if the inversion flag is unset;
• and
• inverting the bits associated with the data stream as the data stream is transferred from the external data source device to the target source, if the inversion flag is set, wherein the data stream is processed and temporarily housed in storage within a same controller as it is transferred to the target source, and wherein the storage is equipped to concurrently house and process additional data streams with the data stream.

A computer readable medium having executable instructions for executing a method which is operable to invert transferred data, the method comprising:

• acquiring a data stream and an inversion flag directly from an external data source device;
• separating the data stream and the inversion flag into a data stream storage and an inversion flag storage;
• and
• buffering one or more additional data streams and one or more additional inversion flags from the data source device in the storages, within a same controller associated with a different device than the data source device, and wherein each device includes its own storage and processing capabilities, and wherein the data stream storage concurrently houses and processes additional data streams with the data stream, and wherein the data stream with a set inversion flag remains unchanged until requested at which time the data stream is inverted as it is transferred out, and wherein the inversion flag storage includes bytes where each bit corresponds to a single unique data stream.

An inversion data transfer system, comprising:

• an external data source device;
• a temporary storage associated with a different device from that of the external data source device;
• and
• a controller that directly transfers a data stream having a plurality of bits from the data source device to the temporary storage, and concurrent to the transfer determines if a total number of set bits within the data stream is more than half of a total number of bits associated with the data stream, and if so associating a set inversion bit with the data stream, otherwise associating an unset inversion bit with the data stream, wherein the temporary storage resides within the controller and on the same device as the temporary storage and separate from the external data source device, and wherein each device includes its own storage and processing capabilities, and wherein the temporary storage is to concurrently handle and process additional data streams with the data stream, and wherein the data stream remains unchanged in the temporary storage when the inversion bit is set until and when it is transferred out of the temporary storage at which time it is inverted, and wherein the inversion bit is part of bytes managed by the controller where each particular bit represents a single unique data stream.

An inversion data transfer system, comprising:

• an external data source device;
• a target source device, wherein the external data source device and the target source device are different from one another and two separate devices, and wherein each device includes its own storage and processing capabilities;
• and
• a controller that directly acquires a data stream and an inversion bit associated with the data stream from the data source device and inverts bits associated with the data stream during a transfer of the data stream to a target source device, if the inversion bit is set, and wherein the controller buffers the data stream before it is transferred to the target source device within the controller, and wherein the controller uses a buffer to buffer the data stream concurrently with additional data streams, and wherein the data stream remains unchanged within the data source device and is inverted when the inversion bit is set and when transferred out of the data source device to the target source device, and wherein the inversion bit is associated with bytes where each bit corresponds to a single unique particular data stream.

A system for transferring a data stream, comprising:

• a control buffer;
• a storage buffer;
• an inversion storage;
• a counting set of executable instructions to count set bits associated with a data stream being received from the control buffer directly into the storage buffer, wherein the control buffer is an external data source to the storage buffer, and the counting set of executable instructions generates an inversion bit associated with the data stream, wherein the inversion bit is housed in the inversion storage and is set if a total number of set bits exceeds more than half a total number of bits associated with the data stream, and wherein the inversion storage, the storage buffer, and the counting set of instructions reside within a same controller and device that is different from another device associated with the control buffer that supplies the data stream, and wherein each device includes its own storage and processing capabilities, and wherein the storage buffer is to concurrently handle and process additional data streams with the data stream, and wherein the data stream remains unchanged in the storage buffer and is inverted when it is transferred out of the storage buffer when the inversion bit is set in the inversion storage, and wherein bytes are maintained in the inversion storage that includes the inversion bit and where each bit corresponds to a single unique data stream.

A flash memory device, comprising:

• a temporary storage;
• a receiving controller;
• a counting controller;
• and
• a transferring controller that transfers a data packet directly received by the receiving controller in a temporary storage to an external target device and further inverts the data packet during the transfer if the counting controller indicates to the transferring controller that the packet requires inversion, wherein the data packet remains unchanged in the temporary storage and is inverted while it is transferred out of the temporary storage when the controller indicates to do so, and wherein the counting controller and the temporary storage reside within the transferring controller device, and wherein each device includes its own storage and processing capabilities, and wherein the temporary storage is concurrently used to house and process other data packets associated with other data streams with the data packet, and wherein an inversion bit is associated with the data packet to indicate to the transferring controller whether the data packet required inversion and a two-byte word includes the inversion bit and each bit of the two-byte word corresponds to single unique data stream.
