Methods and apparatus for designating or using data status indicators

摘要

Memory devices and methods facilitate handling of data received by a memory device through the use of data grouping and assignment of data validity status values to grouped data. For example, data is received and delineated into one or more data groups and a data validity status is associated with each data group. Data groups having a valid status are latched into one or more cache registers for storage in an array of memory cells wherein data groups comprising an invalid status are rejected by the one or more cache registers.

1. A method of operating a memory device, the method comprising:
receiving data at an interface of the memory device from an external device; receiving one or more control signals at the interface from the external device; storing the received data in one or more data groups where each data group is stored in a respective one of a plurality of registers of the memory device; designating a status of each data group responsive to one or more control signals received at the interface; and latching each data group designated as having a first designated status in a data cache of the memory device for writing to a memory array of the memory device.
