Abstract
A column access system is provided with a column counter for producing a column address in response to an external address. The column address is latched in an address decoder which decodes the column address to select a column in the DRAM. A command decoder generates a column decode enable signal supplied to the address decoder to control latching of the column address, and a write enable signal, together with data, supplied to a write driver. A data latch is provided in the write driver for latching data until an equalize control signal is activated. The latched data signal drives global input/output pair to provide data writing to the DRAM.
