摘要： The subject systems and/or methods relate to a high speed memory device that enables a preamble pattern to be updated after manufacture. A high speed memory device can include a FLASH module and a RAM module. The FLASH module can include an initial preamble pattern, wherein the initial preamble pattern is loaded during a power-up of the high speed memory. The RAM module can include a default preamble pattern, wherein the default preamble pattern is loaded after the power-up of the high speed memory. The initial preamble pattern or the default preamble pattern can be defined by a manufacture of the high speed memory or an OEM of the high speed memory. Additionally, the initial preamble pattern or the default preamble pattern can be updated with a customized preamble pattern based upon a target environment.

摘要： One or more embodiments provide a method and system of reading data from a variable-latency memory, via a serial input/output memory data interface. The system includes a memory having a variable-latency access time, a memory controller, and a serial data bus coupling the memory controller to the memory. The memory controller communicates a Read command to the memory and forces the serial data bus low for a limited time. The memory then forces the bus low and the memory controller then releases the bus. When the memory is ready to provide data, the memory provides a high signal on the serial data bus.

摘要： Systems and/or methods are provided that facilitate data capture optimization for devices accessing memories via a bus. In an aspect, a memory can output a read preamble prior to pushing data onto a bus. The read preamble can be a known sequence of one or more bits. A host device accessing the memory via the bus can analyze the read preamble and, particularly, timing characteristics of the read preamble. The timing characteristics can be utilized to identify an optimal capture point within a window of data validity.

摘要： A memory device includes a memory array, an output buffer, an initial latency register, and an output signal. Often times a host device that interfaces with the memory device is clocked at high rate such that data extraction rates of the memory device are not adequate to support a gapless data transfer. 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.
