1. A synchronous sequential access latch array generated by an automated system for generating master-slave latch structures, said latch array comprising:
- N/2 rows of master-slave pairs wherein N is equal to the number of addresses that are included in said latch array;
an N/2 to 1 multiplexer coupled to said N/2 rows of master-slave pairs; and
control logic.

Abstract
A synchronous sequential latch array generated by an automated system for generating master-slave latch structures is disclosed. A master-slave latch structure includes N/2 rows of master-slave latch pairs, an N/2-to-1 multiplexer and control logic. N is equal to the number of latches that are included in the latch array.

11. A method of operating a sequential access memory comprising a master-slave latch pair array, the method comprising:
-
in a second half of a clock cycle, receiving data into an empty and open master latch in a first row of said master-slave latch pair array, if master-slave latch pairs of other rows are empty or if master-slave latch pairs of other rows are full, or receiving data into an empty master latch of a subsequent row of said master-slave latch pair array if a master latch and a slave latch of a row or rows preceding said subsequent row are full; in a first half of a cycle subsequent to a clock cycle in which data is received by a master latch in a row of said master-slave latch pair array, receiving data into a slave latch of said row of said master-slave latch pair array; and providing access to said data received by said slave latch of said row of said master-slave latch pair array. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of operating a sequential access memory comprising a master-slave latch pair array, the method comprising:
-
receiving data into respective master latches in a second half of first respective clock cycles, wherein data that is received in said second half of said first respective clock cycles is allowed to flow uninhibited from respective master latches to respective corresponding slave latches; receiving data into respective master latches in a second half of second respective clock cycles; and providing access to data in said respective corresponding slave latches. - View Dependent Claims (19, 20)
