Abstract: 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.
Abstract: A memory buffering system is disclosed that arbitrates bus ownership through an arbitration scheme for memory elements in chain architecture. A unified host memory controller arbitrates bus ownership for transfer to a unified memory buffer and other buffers within the chain architecture. The system is used within a communication system with a bus in chain architectures and parallel architectures.

Abstract: Based on a continuous erase start signal outputted, in response to an inputted continuous erase command, from a continuous erase control circuit, a shift circuit outputs a control signal for giving instructions to execute respective data erase operation to a plurality of non-volatile memory circuits sequentially, and when the data erase operation in all of the non-volatile memory circuits has been completed, the shift circuit outputs a continuous erase completion signal. Thereby, the data erase operation in all of the non-volatile memory circuits built in one chip can be continuously executed by one continuous erase command as is also the case where a single non-volatile memory circuit is built in.

Abstract: An approach to use silicided bit line contacts that do not short to the underlying substrate in memory devices. The approach provides for silicide formation in the bit line contact area, using a process that benefits from being self-aligned to the oxide-nitride-oxide (ONO) nitride edges. A farther benefit of the approach is that the bit line contact implant and rapid temperature anneal process can be eliminated. This approach is applicable to embedded flash, integrating high density devices and advanced logic processes.

Abstract: Embodiments described herein generally relate to methods of manufacturing n-type lightly doped drains and p-type lightly doped drains. In one method, a photoresist mask is used to etch a transistor, and the mask is left in place (i.e., reused) to protect other devices and poly while a high energy implantation is performed in alignment with the photoresist mask, such that the implantation is adjacent to the etched transistor. One example of a high energy implantation is forming lightly doped source and drain regions. This technique of reusing a photoresist mask can be employed for creating lightly doped source and drain regions of one conductivity followed by using the technique a second time to create lightly doped source and drain regions of the complementary conductivity type. This may prevent use of at least one hard mask during manufacturing.
