Abstract: Systems and/or methods are provided that facilitate employing a variable read latency on a serial memory bus. In an aspect, a memory can utilize an undefined amount of time to obtain data from a memory array and prepare the data for transfer on the serial memory bus. The serial memory bus can be driven to a defined state. When data is ready for transfer, the memory can assert a start bit on the serial memory bus to notify a host prior to initiating the data transfer.

Abstract: Disclosed herein are system, apparatus, methods and/or combinations and sub-combinations thereof, for using a read data strobe signal received at a host device from a peripheral device to convey variable latency (flow) control or report an error in the data content read from the peripheral device. Reception of the read data strobe signal before a predetermined maximum latency time, provides variable latency control back to the host by indicating when valid data is available for capture. If the read data strobe signal is not received before expiration of a predetermined maximum latency time, the peripheral controller is indicating a read data error back to the host.

Abstract: Disclosed is a method for reading from a non-volatile memory (NVM) device including: retrieving a set of data from an NVM array according to a read sequence for a requested set of logical memory locations received from a host device, detecting errors in the set of data, preparing an error indicator to be output to a host device substantially upon detection of the errors and outputting the error indication in response to a command being received from the host device.

Abstract: Disclosed herein are system, method and/or computer program product embodiments for increasing memory bandwidth when accessing a plurality of memory devices. An embodiment operates by executing, by at least one processor, a first read operation to read data from a first memory device following an access time for the first memory device. The embodiment further includes executing, by the at least one processor, a second read operation to read data from a second memory device following an access time for the second memory device. The access time for the second memory device is substantially the same or longer than the access time for the first memory device plus a time it takes to read data from the first memory device.

Abstract: A memory controller is provided. In response to a burst read command that includes a target address, the memory controller provides, to one or more busses, data stored in memory at the target address after dummy clock cycles have occurred. The memory controller also provides a preamble on the bus(ses) during some of the dummy clock cycles. The preamble includes a data training pattern.

Abstract: A memory device is provided. The memory device includes a preamble memory and a memory controller. The preamble memory is arranged to store a read preamble such that the read preamble includes a training pattern that is suitable for aligning a capture point for read data. Further, the training pattern is programmable such that the training pattern can be altered at least once subsequent to manufacture of the preamble memory. In response to a read command, the memory controller provides the read preamble stored in the preamble memory, as well as the read data.

Abstract: A memory device is provided. The memory device includes a preamble disable memory and a memory controller. The preamble disable memory is arranged to store preamble disable data. The preamble disable data includes an indication as to whether a read preamble should be enabled or disabled. In response to a read command, if the preamble disable data includes an indication that the read preamble should be enabled, the memory controller provides the read preamble. Alternatively, in response to the read command, if the preamble disable data includes an indication that the read preamble should be disabled, the memory controller disables the read preamble.

The output signal is operable to stall a transmission between the memory device and the host device when data extraction rates from the memory array are not adequate to support output rates of the output buffer.
