S34ML01G1 PDF Datasheet – 1Gb, SLC NAND Flash Memory

NAND flash memory is a type of non-volatile memory technology that is commonly used in a wide range of electronic devices, including USB drives, memory cards, solid-state drives (SSDs), smartphones, tablets, and more. It is a key component in modern computing and consumer electronics due to its high storage capacity, fast read and write speeds, and low power consumption.

Part Number: S34ML01G1

Function: 1Gb, SLC NAND Flash Memory

Package: VFBGA-63 Pin Type

Manufacturer: Cypress Semiconductor

The Cypress S34ML01G1, S34ML02G1, and S34ML04G1 series is offered with a 3.3-V VCC power supply, and with ×8 or ×16 I/O interface. Its NAND cell provides the most cost-effective solution for the solid state mass storage market. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. The page size for ×8 is
(2048 + 64 spare) bytes; for ×16 (1024 + 32) words.

The chip supports CE# don’t care function. This function allows the direct download of the code from the NAND flash memory device by a microcontroller, since the CE# transitions do not stop the read operation. The devices have a Read Cache feature that improves the read throughput for large files.

During cache reading, the devices load the data in a cache register while the previous data is transferred to the I/O buffers to be read.


1. NAND flash interface
(1) Open NAND Flash Interface (ONFI) 1.0 compliant
