FIELD: printing devices.
SUBSTANCE: proposed invention relates to devices for printing. The fluid ejection unit contains: a set of nozzles for ejecting the current substance, a memory bank having a set of memory blocks arranged in the form of a matrix, the matrix having multiple rows and multiple columns, a bank selection transistor common to multiple memory blocks, and a bank selection transistor serves to facilitate access to a memory block from a set of memory blocks based on the bank selection signal.
EFFECT: proposed solution is aimed at providing an efficient layout that minimizes the amount of space consumed, for example, in a fluid ejection crystal, for implementing various selection registers.
